Derfflinger and Lützow were 210 m ( 689 ft 0 in ) long at the waterline and 210 @.@ 40 m ( 690 ft 3 in ) long overall . Hindenburg was slightly longer , at 212 @.@ 50 m ( 697 ft 2 in ) at the waterline and 212 @.@ 80 m ( 698 ft 2 in ) overall . All three ships had a beam of 29 m ( 95 ft 2 in ) , and a draft of between 9 @.@ 20 m ( 30 ft 2 in ) forward and 9 @.@ 57 m ( 31 ft 5 in ) aft . The first two ships were designed to displace 26 @,@ 600 tonnes ( 26 @,@ 200 long tons ) with a standard load , and up to 31 @,@ 200 tonnes ( 30 @,@ 700 long tons ) at combat weight . Hindenburg displaced slightly more , at 26 @,@ 947 tonnes ( 26 @,@ 521 long tons ) standard and 31 @,@ 500 tonnes ( 31 @,@ 000 long tons ) fully laden . The ships ' hulls were constructed from longitudinal steel frames , over which the outer hull plates were riveted . Derfflinger 's hull contained 16 watertight compartments , though Lützow and Hindenburg had an additional seventeenth compartment . All three ships had a double bottom that ran for 65 % of the length of the hull . This was a decrease from preceding German battlecruisers , which had a double bottom for at least 75 % of the hull .

The ships were regarded as excellent sea boats by the German navy . The Derfflinger @-@ class ships were described as having had gentle motion , though they were " wet " at the casemate deck . The ships lost up to 65 % speed with the twin rudders hard over , and heeled up to 11 degrees . This was greater than any of the preceding battlecruiser designs , and as a result , anti @-@ roll tanks were fitted to Derfflinger . The three ships had a metacentric height of 2 @.@ 60 m ( 8 ft 6 in ) . The standard crew for one of the vessels was 44 officers and 1 @,@ 068 men ; when serving as the flagship for the I Scouting Group , the ships carried an additional 14 officers and 62 men . The Derfflingers carried smaller craft , including one picket boat , three barges , two launches , two yawls , and two dinghies .

By the time construction work on Derfflinger began , it was determined that the diesel engine was not ready for use . Instead , the plan to use a three @-@ shaft system was abandoned and the ships reverted to the standard four @-@ shaft arrangement . Each of the three ships were equipped with two sets of marine @-@ type turbines ; each set drove a pair of 3 @-@ bladed screws that were 3 @.@ 90 m ( 12 ft 10 in ) in diameter on Derfflinger and Lützow and 4 m ( 13 ft 1 in ) in diameter on Hindenburg . Each set consisted of a high- and low @-@ pressure turbine — the high @-@ pressure machines drove the outer shafts while the low @-@ pressure turbines turned the inner pair . Steam was supplied to the turbines from 14 coal @-@ fired marine @-@ type double boilers and eight oil @-@ fired marine @-@ type double @-@ ended boilers . Each ship was equipped with a pair of turbo @-@ electric generators and a pair of diesel @-@ electric generators that provided a total of 1 @,@ 660 kilowatts at 220 volts . Each ship was equipped with two rudders .

The engines for first two ships were designed to provide 62 @,@ 138 shaft horsepower ( 46 @,@ 336 kW ) , at 280 revolutions per minute . This would have given the two ships a top speed of 26 @.@ 5 knots ( 49 @.@ 1 km / h ; 30 @.@ 5 mph ) . During trials , Derfflinger 's engines achieved 75 @,@ 586 shp ( 56 @,@ 364 kW ) , but a top speed of 25 @.@ 5 knots ( 47 @.@ 2 km / h ; 29 @.@ 3 mph ) . Lützow 's engines reached 79 @,@ 880 shp ( 59 @,@ 570 kW ) and a top speed of 26 @.@ 4 knots ( 48 @.@ 9 km / h ; 30 @.@ 4 mph ) . Hindenburg 's power plant was rated at 71 @,@ 015 shp ( 52 @,@ 956 kW ) at 290 rpm , for a top speed of 27 knots ( 50 km / h ; 31 mph ) . On trials she reached 94 @,@ 467 shp ( 70 @,@ 444 kW ) and 26 @.@ 6 knots ( 49 @.@ 3 km / h ; 30 @.@ 6 mph ) . Derfflinger could carry 3 @,@ 500 t ( 3 @,@ 400 long tons ) of coal and 1 @,@ 000 t ( 980 long tons ) of oil ; at a cruising speed of 14 knots ( 26 km / h ; 16 mph ) , she had a range of 5 @,@ 600 nautical miles ( 10 @,@ 400 km ; 6 @,@ 400 mi ) . Lützow carried 3 @,@ 700 t ( 3 @,@ 600 long tons ) of coal and 1 @,@ 000 tons of oil , though she had no advantage in range over her sister Derfflinger . Hindenburg also stored 3 @,@ 700 tons of coal , as well as 1 @,@ 200 t ( 1 @,@ 200 long tons ) of oil ; her range at 14 knots was rated at 6 @,@ 100 nautical miles ( 11 @,@ 300 km ; 7 @,@ 000 mi ) .

The Derfflinger @-@ class ships were armed with eight 30 @.@ 5 cm ( 12 in ) SK L / 50 guns in four twin gun turrets , two forward of the main superstructure in a superfiring pair and two to the rear of the ship , in a similar arrangement . The guns were housed in Drh.L C / 1912 mounts on the first two ships , and in Drh.L C / 1913 mounts on Hindenburg . The turrets were trained with electric motors , while the guns were elevated hydraulically , up to 13 @.@ 5 degrees . The guns fired 405 @.@ 5 @-@ kilogram ( 894 lb ) armor @-@ piercing shells at a muzzle velocity of 855 meters per second ( 2 @,@ 805 ft / s ) . At 13 @.@ 5 degrees , the shells could hit targets out to 18 @,@ 000 m ( 20 @,@ 000 yd ) . The turrets were modified in 1916 to increase the elevation maximum to 16 degrees . This correspondingly increased the range to 20 @,@ 400 m ( 22 @,@ 300 yd ) . The ships carried 720 shells , or 90 per gun ; each gun was supplied with 65 armor @-@ piercing ( AP ) shells and 25 semi @-@ AP shells for use against targets with less armor protection . The 30 @.@ 5 cm gun had a rate of fire of between 2 – 3 shells per minute , and was expected to fire 200 shells before replacement was necessary . The guns were also capable of firing 405 @.@ 9 kg ( 894 @.@ 8 lb ) high explosive shells . The shells were loaded with two RP C / 12 propellant charges : a main charge in a brass cartridge that weighed 91 kg ( 201 lb ) and a fore charge in a silk bag that weighed 34 @.@ 5 kg ( 76 lb ) . The propellant magazines were located underneath the shell rooms for the two forward turrets as well as the rear superfiring turret ; the arrangement was reversed for the rearmost turret .

The ships were designed to carry fourteen 15 cm ( 5 @.@ 9 in ) SK L / 45 guns , mounted in casemates along the superstructure . Because Derfflinger had to be fitted with anti @-@ roll tanks , two of the casemated guns had to be removed , to allow enough room in the hull . Lützow and Hindenburg were equipped with the designed number of guns . Each gun was supplied with 160 rounds , and had a maximum range of 13 @,@ 500 m ( 14 @,@ 800 yd ) , though this was later extended to 16 @,@ 800 m ( 18 @,@ 400 yd ) . The guns had a sustained rate of fire of five to seven rounds per minute . The shells were 45 @.@ 3 kg ( 99 @.@ 8 lb ) , and were loaded with a 13 @.@ 7 kg ( 31 @.@ 2 lb ) RPC / 12 propellant charge in a brass cartridge . The guns fired at a muzzle velocity of 835 meters per second ( 2 @,@ 740 ft / s ) . The guns were expected to fire around 1 @,@ 400 shells before they needed to be replaced .

The three ships carried a variety of 8 @.@ 8 cm ( 3 @.@ 5 in ) SK L / 45 guns in several configurations . The Derfflinger @-@ class ships were initially equipped with eight of these weapons , all in single mounts ; four were placed in the forward superstructure and four in the aft superstructure . The ships also carried four 8 @.@ 8 cm Flak L / 45 anti @-@ aircraft guns , which were emplaced around the forward funnel , with the exception of Lützow , which carried the Flak guns around the rear funnel . After 1916 , the four 8 @.@ 8 cm guns in the forward superstructure were removed . The Flak guns were emplaced in MPL C / 13 mountings , which allowed depression to − 10 degrees and elevation to 70 degrees . These guns fired 9 kg ( 19 @.@ 8 lb ) shells , and had an effective ceiling of 9 @,@ 150 m ( 30 @,@ 019 ft 8 in ) at 70 degrees .

The ships were also armed with submerged torpedo tubes in their hulls . Derfflinger was equipped with four 50 cm tubes ; the later ships were armed with more powerful 60 cm weapons . The tubes were arranged with one in the bow , one in the stern , and two on the broadside . Derfflinger 's 50 cm torpedoes were the G7 type , 7 @.@ 02 m ( 276 in ) long and armed with a 195 kg ( 430 lb ) Hexanite warhead . The torpedo had a range of 4 @,@ 000 m ( 4 @,@ 370 yd ) when set at a speed of 37 knots , and up to 9 @,@ 300 m ( 10 @,@ 170 yd ) at 27 knots . The 60 cm torpedoes were the H8 type , which were 8 m long and carried a 210 kg ( 463 lb ) Hexanite warhead . The torpedoes had a range of 6 @,@ 000 m ( 6 @,@ 550 yd ) when set at a speed of 36 knots ; at a reduced speed of 30 knots , the range increased significantly to 14 @,@ 000 m ( 15 @,@ 310 yd ) .

The Derfflinger @-@ class ships were protected with Krupp cemented steel armor , as was the standard for German warships of the period . They had an armor belt that was 300 mm ( 12 in ) thick in the central citadel of the ship , where the most important parts of the ship were . This included the ammunition magazines and the machinery spaces . The belt was reduced in less critical areas , to 120 mm ( 4 @.@ 7 in ) forward and 100 mm ( 3 @.@ 9 in ) aft . The belt tapered down to 30 mm ( 1 @.@ 2 in ) at the bow , though the stern was not protected by armor at all . A 45 mm ( 1 @.@ 8 in ) thick torpedo bulkhead ran the length of the hull , several meters behind the main belt . The main armored deck ranged in thickness from 30 mm thick in less important areas , to 80 mm ( 3 @.@ 1 in ) in the sections that covered the more critical areas of the ship .

The forward conning tower was protected with heavy armor : the sides were 300 mm thick and the roof was 130 mm ( 5 @.@ 1 in ) thick . The rear conning tower was less well armored ; its sides were only 200 mm ( 7 @.@ 9 in ) thick and the roof was covered with 50 mm ( 2 @.@ 0 in ) of armor plate . The main battery gun turrets were also heavily armored : the turret sides were 270 mm ( 11 in ) thick and the roofs were 110 mm ( 4 @.@ 3 in ) thick . On Hindenburg , the thickness of the turret roofs was increased to 150 mm ( 5 @.@ 9 in ) . The 15 cm guns had 150 mm @-@ worth of armor plating in the casemates ; the guns themselves had 70 mm ( 2 @.@ 8 in ) thick shields to protect their crews from shell splinters .

Of the three ships in its class , only Derfflinger was ordered as an addition to the fleet , under the provisional name " K " . The other two ships were to intended to replace obsolete vessels ; Lützow was ordered as Ersatz Kaiserin Augusta for the elderly protected cruiser Kaiserin Augusta and the contract for Hindenburg was issued under the provisional name Ersatz Hertha , to replace the protected cruiser Hertha .

Derfflinger was constructed at Blohm & Voss in Hamburg under construction number 213 . She was the least expensive of the three ships , at a cost of 56 million gold marks . The ship was ready to be launched on 14 June 1913 , but during the ceremony , one of the wooden sledges upon which the hull rested became jammed . It took until 12 July for her to enter the water . She was commissioned into the High Seas Fleet on 1 September 1914 , shortly after the outbreak of World War I. Lützow was built at the Schichau dockyard in Danzig under construction number 885 , at the cost of 58 million gold marks . The ship was launched on 29 November 1913 , and after lengthy trials , commissioned on 8 August 1915 . Hindenburg , the final member of the class , was built at the Imperial Dockyard in Wilhelmshaven , under construction number 34 . The ship was built at a cost of 59 million gold marks , the most expensive of the three vessels . She was launched on 1 August 1915 and commissioned on 10 May 1917 .

Named after Georg von Derfflinger , a German field marshal during the Thirty Years ' War , Derfflinger was commissioned on 1 September 1914 . A dockyard crew transferred the ship from Hamburg to Kiel , via the Skagen . The ship was assigned to the I Scouting Group at the end of October . Damage to the ship 's turbines sustained during trials prevented the ship from seeing active service until 16 November . On 15 December , the ship took part in the raid on Scarborough , Hartlepool and Whitby . She was also present during the battle of Dogger Bank on 24 January 1915 . The ship was hit once by a 13 @.@ 5 @-@ inch shell from one of the British battlecruisers ; in response , she heavily damaged HMS Lion . Repair work was completed by 16 February , but Derfflinger 's starboard turbine was accidentally damaged on 28 June , and the ship was again in the dockyard until August . On 24 April 1916 , Derfflinger took part in the bombardment of Yarmouth .

On 31 May , Derfflinger was heavily engaged during the Battle of Jutland , as the second ship in the German battlecruiser line . She sustained 21 major hits during the battle , but dealt considerable damage to the British battlecruiser force as well . At 16 : 26 , HMS Queen Mary sank after a magazine explosion that tore the ship apart ; she had been targeted with a hail of heavy @-@ caliber gunfire from Derfflinger and Seydlitz . Two hours later , at 18 : 30 , HMS Invincible suffered a similar fate , though Derfflinger was assisted by her sister Lützow . During the engagement , Derfflinger had both of her rear turrets knocked out by British gunfire . Her crew suffered 157 men killed and 26 wounded , which was the highest casualty figure for any German ship not sunk . The resilience of the vessel earned her the nickname " Iron Dog " from her British adversaries . Repair work lasted until 15 October , during which the ship had her pole mast removed and replaced with a tripod mast . The ship conducted training operations until November , at which point she returned to active duty with the fleet .

Following the German capitulation in November 1918 , Derfflinger was interned with a significant portion of the High Seas Fleet in Scapa Flow . On 21 June 1919 , with the guard ships of the Royal Navy out on maneuvers , Rear Admiral Ludwig von Reuter ordered that the fleet be scuttled . The resulting scuttling of the German fleet saw some 66 vessels of various types sunk . Among those was Derfflinger , which sank at 14 : 45 . The ship was raised in 1939 to be broken up for scrap metal , but the outbreak of World War II intervened . The ship , which remained capsized , was anchored off the island of Risa until 1946 , at which point she was sent to Faslane Port , where she was broken up . The ship 's bell was delivered to the German Federal Navy on 30 August 1965 .

Lützow was named after Ludwig Adolf Wilhelm von Lützow , a Prussian lieutenant @-@ general who fought during the Napoleonic Wars . The ship was commissioned on 8 August 1915 , and then underwent trials . On 25 October , while still running sea trials , Lützow 's port low pressure turbine were severely damaged . She was sent to Kiel for repairs , which lasted until late January 1916 . The ship went on additional trials that lasted until 19 February . Lützow was by then fully operational , and assigned to the I Scouting Group on 20 March 1916 . She took part in two fleet advances , on 25 March and 21 – 22 April , without any major incidents . The following day , on 23 April , Lützow , along with her sister Derfflinger and the battlecruisers Seydlitz , Moltke , and Von der Tann , bombarded Yarmouth . While en route to the target , Vice Admiral Franz von Hipper 's flagship Seydlitz was heavily damaged by mines . As a result , Lützow was transferred to the role of squadron flagship . During the operation , the German battlecruisers encountered British light forces , and a running battle ensued . Lützow engaged the light cruiser HMS Conquest and hit her several times .

At the Battle of Jutland , she was the first ship in the German line , and Hipper 's flagship , and drew fire from the British battlecruisers which included hits below her waterline . Shortly after the start of the battlecruiser action , Lützow hit her opponent Lion several times ; one hit knocked out Lion 's " Q " turret , and the resulting magazine fire nearly destroyed the ship . Shortly after 19 : 00 , the armored cruisers Defence and Warrior inadvertently ran into the German line ; Lützow opened fire immediately , followed by several German dreadnoughts . In a hail of shells , Defence 's ammunition magazines detonated and the ship was sunk . At around the same time , the fresh battlecruisers of the 3rd Battlecruiser Squadron engaged their German opposites . Between 19 : 26 and 19 : 34 , Lützow sustained four 12 @-@ inch shell hits in her bow from the British battlecruisers ; these eventually proved to be fatal . Despite this , at 19 : 30 , the combined fire of Lützow and her sister Derfflinger destroyed the battlecruiser Invincible . By 20 : 15 , Lützow had been hit five more times , including hits on her two forward turrets .

21,473
By 22 : 15 , Lützow had shipped nearly 2 @,@ 400 tons of water , and the ship was dangerously down by the bows . After midnight , attempts were made to steer the ship in reverse . This failed when the bow became submerged enough to bring the stern out of the water ; by 02 : 20 , the screws and both rudders were coming out of the water and the ship was no longer able to steer . The order to abandon ship was given , and at 02 : 47 , Lützow was sunk by the torpedo boat G38 . The ship was lost because the flooding in the bow could not be controlled ; the forward pump system failed and the central system could not keep up with the rising water . The crew was picked up by four torpedo boats that had been escorting the crippled battlecruiser ; during the battle the ship suffered 116 men killed .

Hindenburg was the last battlecruiser completed for the Imperial German Navy , and as such had a very short career . She was commissioned 10 May 1917 , and was fully operational by 20 October 1917 , too late to see any major action in World War I. On 17 November Hindenburg and Moltke , along with the light cruisers of the II Scouting Group , were acting as distant support for German minesweepers off the German coast when they were attacked by British battlecruisers . The raid was brief ; by the time Hindenburg and Moltke arrived on the scene , the British ships had broken off the attack and withdrawn . Six days later , Hindenburg replaced Seydlitz as flagship of the I Scouting Group . On 23 April 1918 , the ship took part in an abortive fleet advance into the North Sea that attempted to intercept an Allied convoy . Moltke sustained mechanical damage while en route , and as a result , Vice Admiral Hipper decided to cancel the operation . On 11 August , Hipper was promoted to Admiral and given command of the entire High Seas Fleet . Rear Admiral Ludwig von Reuter replaced Hipper as the commander of the I Scouting Group ; he raised his flag on Hindenburg the following day .

Hindenburg was interned at Scapa Flow , along with her sister Derfflinger and the rest of the German battlecruisers . She was scuttled on 21 June 1919 , and sank at 17 : 00 . Several unsuccessful attempts to raise her were made ; on 23 July 1930 the ship was finally raised . From 1930 to 1932 she was scrapped at Rosyth . Her bell was presented to the German Federal Navy on 28 May 1959 .

The O 'Brien class of destroyers was a class of six ships designed by and built for the United States Navy shortly before the United States entered World War I. The O 'Brien class was the third of five classes of destroyers that were known as the " thousand tonners " , because they were the first U.S. destroyers over 1 @,@ 000 long tons ( 1 @,@ 016 t ) displacement .
96d7194281d8a2b220dcd42f4ebd99d5
21,484
The design of what became the O 'Brien class was the result of discussions between the General Board of the United States Navy and the U.S. Navy 's Bureau of Ordnance . What resulted was a design that was an incremental development of the Aylwin class , which itself was similar to the first of the thousand tonners , the Cassin class ( which displaced about a third more than the preceding Paulding class ) . The key difference in the O 'Brien class was the increase in torpedo size , going up to 21 inches ( 533 mm ) from the preceding classes ' 18 @-@ inch ( 457 mm ) torpedoes .
d0988c1f02be5fd1d57d7585802b1e8b
21,485
The ships had a median displacement of 1 @,@ 050 long tons ( 1 @,@ 070 t ) , were just over 305 feet ( 93 m ) in length , and had a beam of about 31 feet ( 9 @.@ 4 m ) . All of the ships had two direct @-@ drive steam turbines and a combination of other engines for cruising at speeds less than 15 knots ( 28 km / h ) . All of the ships were designed for a maximum speed of 29 knots ( 54 km / h ) . As built , they were armed with four 4 @-@ inch ( 102 mm ) guns and had four twin 21 @-@ inch torpedo tubes with a load of eight torpedoes , but all were later equipped with depth charges . The ships were built by four private American shipyards — Bath Iron Works , Fore River Shipbuilding Company , New York Shipbuilding Corporation , and William Cramp and Sons — and were laid down between September and November 1913 ; launched between April 1914 and February 1915 ; and commissioned into the U.S. Navy between June 1914 and August 1915 .

All six ships operated in the Atlantic or Caribbean until the U.S. entrance into World War I in April 1917 , when all six were sent overseas to Queenstown , Ireland , for convoy escort duties . Several of the ships rescued passengers and crew from ships sunk by U @-@ boats , and several had encounters with U @-@ boats themselves ; Nicholson helped sink U @-@ 58 in November 1917 , the first U @-@ boat sunk by the U.S. Navy . All six members of the class had returned to the United States in January 1919 and were decommissioned by June 1922 . In 1924 , two of the six — Ericsson and McDougal — were commissioned into the United States Coast Guard to help enforce Prohibition as a part of the " Rum Patrol " . They were returned to U.S. Navy custody in 1932 and 1933 , respectively . All six ships had been sold for scrapping by June 1936 .

For the 1913 fiscal year , the General Board of the United States Navy determined that six destroyers would be authorized . The design for Destroyers No. 51 through No. 56 — what became the O 'Brien class , was to closely follow the design of the Cassin and Aylwin classes from fiscal year 1912 . The chief of the U.S. Navy 's Bureau of Ordnance ( BuOrd ) suggested that the new destroyers be equipped with ten torpedo tubes and urged that the new 21 @-@ inch ( 533 mm ) torpedo be adopted . The General Board agreed in principle , adopting the 21 @-@ inch torpedo tubes , but eliminated BuOrd 's proposed centerline torpedo tubes and keeping the number of tubes at eight , the same as the Cassin and Aylwin classes . The additional weight of the larger torpedoes , 5 long tons ( 5 @.@ 1 t ) of top weight , was offset by reducing the planned two aft @-@ facing guns to a single one . This gave the class four 4 @-@ inch ( 102 mm ) guns , which , again , matched the battery of the Cassin and Aylwin classes . The design for the O 'Brien class was approved on 20 August 1912 , and authorized by Congress on 4 March 1913 .

As built , the O 'Brien @-@ class ships were 305 feet 5 inches ( 93 @.@ 09 m ) in length ( overall ) , were 31 feet 2 inches ( 9 @.@ 50 m ) abeam , and had a standard draft of 9 feet 6 inches ( 2 @.@ 90 m ) . The hull shape featured the distinctive high forecastle typical of U.S. destroyer classes since the 1908 – 09 Smith class , the first destroyers designed to be truly ocean @-@ going vessels . The ships displaced between 1 @,@ 020 and 1 @,@ 090 long tons ( 1 @,@ 040 and 1 @,@ 110 t ) with a median of 1 @,@ 050 long tons ( 1 @,@ 070 t ) .

The ships were equipped with two propeller shafts and two direct @-@ drive , Zoelly steam turbines fed by four White @-@ Forster boilers . The power plant of the ships generated 17 @,@ 000 shaft horsepower ( 13 @,@ 000 kW ) which drive the ships to the design speed of 29 knots ( 54 km / h ) . Because of inherent inefficiency of turbines at low speeds , all of the ships were equipped with supplemental cruising engines for travel at speeds under 15 knots ( 28 km / h ) . All except Cushing were equipped with supplemental triple @-@ expansion reciprocating engines : O 'Brien , Nicholson , and Winslow each had a pair of reciprocating engines for cruising ; McDougal and Ericsson were outfitted with only one . Instead of reciprocating engines , Cushing was equipped with a pair of geared steam turbines for cruising .

The main battery of the O 'Brien class consisted of four 4 @-@ inch ( 100 mm ) / 50 Mark 9 guns , with each gun weighing in excess of 6 @,@ 100 pounds ( 2 @,@ 800 kg ) . The guns fired 33 @-@ pound ( 15 kg ) armor @-@ piercing projectiles at 2 @,@ 900 feet per second ( 880 m / s ) . At an elevation of 20 ° , the guns had a range of 15 @,@ 920 yards ( 14 @,@ 560 m ) .

21,497
The O 'Brien ships were also equipped with four twin 21 @-@ inch ( 533 mm ) torpedo tubes , for a total load of eight Mark 8 torpedoes . Although the General Board had called for two anti @-@ aircraft guns for the O 'Brien class , they were not originally outfitted with the weapons ; the later Sampson class was the first American destroyer class so armed . Likewise , there is no record of any of the O 'Brien ships being outfitted with mine @-@ laying apparatus . During World War I , most American destroyers were used in anti @-@ submarine warfare roles , and were equipped with depth charges and delivery systems , such as Y @-@ guns and depth charge racks . O 'Brien @-@ class ships were equipped with depth charges during the war , but no specific mentions of the types of depth charges used or delivery system are recorded in secondary sources .

The " thousand tonners " were the 26 United States Navy destroyers of five classes — Cassin , Aylwin , O 'Brien , Tucker , and Sampson — so named because they were the first U.S. Navy destroyers to have displacements greater than 1 @,@ 000 long tons . The Cassin class , the first of the thousand tonners , displaced about a third more than the preceding Paulding class . The introduction of the thousand tonners led to the Pauldings and other older , smaller displacement destroyers of previous classes to be dismissively called " flivvers " , a nickname also commonly applied to the Ford Model T.

The O 'Brien class was the third of the five classes of " thousand tonners " . The earlier Cassin- ( DD @-@ 43 to DD @-@ 46 ) and Aylwin @-@ class ( DD @-@ 47 to DD @-@ 50 ) ships were about the same length as the O 'Brien ships and all had median displacements in the range of 1 @,@ 020 – 1 @,@ 050 long tons ( 1 @,@ 040 – 1 @,@ 070 t ) ; the later Tucker- ( DD @-@ 57 to DD @-@ 62 ) and Sampson @-@ class ( DD @-@ 63 to DD @-@ 68 ) ships were about 10 feet ( 3 @.@ 0 m ) longer and had median displacements of 1 @,@ 090 – 1 @,@ 100 long tons ( 1 @,@ 110 – 1 @,@ 120 t ) . All five classes were armed with four 4 @-@ inch ( 102 mm ) guns , but the torpedo size and complement varied . All were equipped with four twin torpedo tubes loaded with eight torpedoes except for the Sampsons ( which had four triple tubes carrying twelve torpedoes ) , but the Cassin and Aylwin classes were armed with 18 @-@ inch ( 457 mm ) torpedoes . The O 'Brien ships were the first armed with the new21 @-@ inch ( 533 mm ) Mark 8 torpedoes ; the Tucker and Sampson ships also used the 21 @-@ inch torpedoes . The Sampsons were the only group originally equipped with anti @-@ aircraft guns , a pair of 1 @-@ pounder ( 0 @.@ 45 kg ) guns with a caliber of 37 mm ( 1 @.@ 46 in ) .

The construction of the six O 'Brien @-@ class ships was allocated to four U.S. shipbuilders . William Cramp constructed a trio of O 'Brien destroyers , while the Fore River Shipbuilding Company , Bath Iron Works , and New York Shipbuilding Corporation built one ship each . The keels for all six ships were laid down between July and November 1913 , with McDougal being the first and Ericsson the last . All were launched between April 1915 and January 1915 , with McDougal again being the first and Winslow being the last . McDougal was commissioned in June 1914 , two months after her launch ; the rest were commissioned between April and August 1915 , with Cushing the final ship to enter service . The cost of each ship for hull and machinery was $ 790 @,@ 000 .

All six members of the class served in the Atlantic or Caribbean throughout their U.S. Navy careers . In October 1916 , with the United States still neutral in World War I , five of the six class members ( all except Nicholson ) were among the U.S. destroyers sent out to rescue survivors from five ships torpedoed by German submarine U @-@ 53 off the Lightship Nantucket .

After the United States entered the war in April 1917 , all six class members were sent overseas to Queenstown , Ireland , for convoy escort and anti @-@ submarine duties . McDougal was in the first group of six American destroyers that arrived at Queenstown on 4 May ; Ericsson and Winslow followed in the second group , which arrived thirteen days later , and Cushing , Nicholson , and O 'Brien in the third group , a week after that . Several of the ships had encounters with U @-@ boats during the war : Nicholson , working with Fanning in November 1917 , helped to sink U @-@ 58 , which was the first U @-@ boat sunk by the U.S. Navy ; earlier , in June , O 'Brien had depth @-@ charged U @-@ 16 and was thought by the British Admiralty to have seriously damaged the U @-@ boat , but post @-@ war analysis of records showed that U @-@ 16 survived the attack and returned safely to port .

All six ships returned to the United States in January 1919 and served in various roles over the next two years . Cushing was decommissioned in August 1920 , followed by Nicholson and McDougal in May 1922 , and the remaining three in the following month . In June 1924 , two of the six ships — Ericsson and McDougal — were reactivated for service with the United States Coast Guard 's " Rum Patrol " . Ericsson was returned to the U.S. Navy in May 1932 , and McDougal in June 1933 ; both were sold for scrapping in 1934 . O 'Brien was sold for scrapping in 1935 , and the remaining three in June 1936 .

According to Casting Crowns ' lead singer Mark Hall , the idea for " Who Am I " came while he was driving home with his wife and children one night . Hall , who was having personal worship time during the drive , recounts that he wondered " Who am I to think I can just call up to God whenever I want , from the middle of nowhere , and expect Him to hear me ? " Hall says " immediately I started thinking I 'm a new creation , I 'm more than a conqueror ... I 'm [ also ] grass , that is rises up and is gone in a day " . In an interview , he commented that " me being a conqueror is true , but at the same time I need to understand that my life is a vapor , and me being able to even pray to [ God ] is because of what he 's done for me " . " Who Am I " was produced by Mark A. Miller and Steven Curtis Chapman . It was recorded at Glow In The Dark Studio in Decatur , Georgia and Zoo Studio in Franklin , Tennessee , and it was engineered by Matt Goldman and Sam Hewitt .
