These 12 ships were the last US prewar destroyers class (completed before Dec. 1941). They marked a turning point, leaving behind theoretical considerations and naval staff ideas for a more pragrmatic approach, both dictated by captains reports and taking advantage of tonnages revisions brought by the the Second London Naval Treaty in 1935, lifting some limits. Not to start completely anew, it was chosen to base the new tonnage on the previous Benham class, being 70 tons more and pregmatic in their approach, notably making a return to artillery versus torpedo load. All Sims-class destroyers saw heavy action in WW2 on all theaters, with almost half lost in combat, and accumulating 91 battle stars.

The last prewar US destroyers

The twelve Sims class were the continuation of the Mahan, but with many differences: They marked a new standard, away from the mistakes of the previous Gridley-Bagley-Benham. In 1937, when their genesis began, the second treaty of London was ratified, which noted limitations in tonnage for destroyers, both global and with a reevaluated displacement of 3,000 tons. The Sims were studied by the CNO (Chief of Naval Operations), formulating a new standard based on existing design's experiences and reports. The new design was to leave the prevailing theoretical system so far (notably the heavy torpeo tubes load). Instead, critics and wishes of destroyers commanders was taken in account and they would be more pragmatic in their approach.

Paradoxically, the tonnage boost still was combined with four torpedo tube banks and they ended better armed, larger and heavier, but still on a 1500 tons base and so the design was already theoretically unstable. Stability problems were only solved, at the cost of many modifications advocated by the newly established Bureau of Ship (BuShips).

The Bureau of Ships was setup in 1940 and replaced the two competing organizations (Bureau of Ships and Repairs or BuC&R and Bureau of Engineering or BuEng). A third one, the Bureau of Ordnance, still took care of the equipments, armor, guns and mounts, and also intervened on its field during the design phase.

The start was poor communication between the two. Indeed, the new class were increased by 8 feet (2.4 m) in hull length to take advantage of the extra tonnage (with benefits on seaworthiness -by better coping with wavelenghts-, speed -by increasing the hull ratio- and range -by having more space for bunkerage). Thus started a trend of upsizing, later trigerred by the fall of all lmits -war obliges- leading to the 2100-ton destroyers of wartime. The Bensons and Gleaves, and of course the Fletchers.

The class was designed by Gibbs & Cox of New York, already behind many innovative destroyer designs. They incorporated streamlining of the bridge structure, forward hull, to further increase speed, improving fuel economy while keeping roughly the same machinery arrangement as before, but with a more powerful powerplant (which ended heavier as well). Based on captains demands, they managed to add an additional 5-inch gun. However torpedo tubes were rearranged in a trio, two broadside quad banks and one elevated on centerline, keeping the 8 torpedo broadside, but no longer the theoretical forward launch of 12 torpedoes (16 before).

Implicated in these debates, the Admiralty Board also wanted a fifth gun according to a specific design: They wanted destroyers tailored for the Pacific. The fifth 5-in (127 mm) gun was required to better face the "special type" IJN destroyers. In addition, these main guns were partly in enclosed turrets; The two superfiring forward and the aftmost. As for machinery they kept the single funnel of past designs.

So what was wrong ?
When USS Anderson, the first of the class to be delivered in February 1939 was inspected at Federal Shipbuilding, Kearny, New Jersey, it was found to be 150 tons overweight, and thus dangerously top-heavy due to insufficient metacentric height already before making her sea trials. This trigerred an order to stop construction of the whole serie while a complete redesign and even rebuilding of the class (so delays and costs). This infuriated both the president and Navy state secretary, Charles Edison.

It was decided out of emergency to drop one of the 5-inch (127 mm) guns, the third, and rearranged the torpedo tubes. One side mount was removed, the other relocated to the centerline, so having two quadruple centerline, but elevated on the structure. This has been an underestimation by the Bureau of Engineering, of the weight of a new machinery design and the Bureau of Construction and Repair did not have sufficient authority to detect or correct the error during the design process...

Secretary of the Navy Charles Edison thus also proposed to have the two bureaus merged into the "Bureau of Ships". However as the two bureau chiefs could not agree he fired them in September 1939. The administrative change was ratified by a law passed by Congress on 20 June 1940. A single entity will prevent from now on any miscommunication and ensured this mishap never happen again.

Detailed Design:

Eventually the new design was approved, changed were made and construction resumed (see later).

Hull and general design

The Sims class displaced still 1,570 tons (light standard) but for 2,293 tons (full load) so more than the previous designs, with a 348 ft 3 in (106.15 m) hull overall, 36 ft 1 in (11 m) in beam and 13 ft 4 in (4.06 m) in draft. The rest was pretty much a repeat of the Benhams, with a single pol mast aft of their redesigned bridge. The latter was probably the most thought after part of the design, as per Gibbs & Cox work. instead of the classic triangular shaped generous winged bridge from the past (first adopted by the Farraguts and repeated since, inherited from the Flush Deckers and going back way before), they chose a completely different approach, dictated by speed: A streamlined bridge.

Also they choose to drop the generous "glasshouse" which made great view in peacetime, but was a hinderance in case of combat. In heavy weather it was not unheard of of these shattering, and in cas of wartime, they would have been the source of glass shards projected inside, thus injuring all key personal. Instead, captained asked for smaller apertures, arguing that they would in normal times rather be on the wings. The end result was a unique combination of a rounded bridge with portholes (less glass, mor eprotection and rigidity) wich proved more economical also, still an open bridge above, and two also streamlined wings, but extending not further than the sides of the forward superstructure. That style of bridge was repeated on the Bensons, Gleaves and Fletcher, before being changed on the Sumner/Gearing. The prow was still rather tall for seaworthiness, the changes being mostly in the hull entry lines. Portholes were kept also. USS Russel in 1943. Note she kept N°3 main gun.

Powerplant

First destroyer completed, USS Anderson in sea trials, 1939.
The Sims nearly duplicated the advanced machinery of the preceding Benham class. They had boiler rooms adjacent forward, engine rooms adjacent aft, one funnel. This was the last time this arrangement was repeated. Steam pressure was still 600 psi (4,100 kPa) (sometimes 565 psi in sources perhaps a builder's variation). That spea was superheated to 715 °F (379 °C) and boiler economizers added as well as double reduction gearing by Westinghouse plus cruising turbines. The while panoply ensure better efficiency for range, maintained great speed, with a base output of 51,138 shp (38,134 kW) in trials versus 49,250 shp (36,730 kW) for the Benhams.

Net result was a speed on 37 knots (69 km/h; 43 mph) on trials, versus 37.9 knots (70.2 km/h; 43.6 mph) on trials so not that great a gain for having less torpedoes nor more guns in the end. As for range, they were still able to travel 5,640 nmi (10,450 km; 6,490 mi) at 12 knots (22 km/h; 14 mph) versus 5,390 nmi (9,980 km; 6,200 mi) at the same, so not that great improvement either. Apart the design bridge in general, there was not much to like as for improvements on this class.



The class in 1939 and 1942

Armament

Main

Mark 25 enclosed mounts.

Initially as said, five 5 inch (127 mm)/38 caliber guns initially, all centerline, two superfiring forward and same aft, and one located on the quarterdeck aft. Later in 1941 this extra mount as removed whenever possible, replaced by extra AA. But this was not systematic, a few ships kept all five for some extra time after December 1941. The novelty was the addition of Mark 25 Mod 0 enclosed mounts for three of these (initially all five, buy this was revised due to weight issues, mount 3 and 4 being of the old open type. These guns were dual purpose ones, anti-surface and anti-aircraft.

Torpedo Tubes

Initially 12 × 21 inch (533 mm) torpedo tubes (3 × 4) (one mount centerline). The class proved to be top-heavy and thus one quadruple torpedo mount was removed in early 1941, with the early units ships still completed with 12 torpedo tubes (three quad mounts with one mounted centerline, others on deck port and starboard). They were modified later (summer 1940, USS Sims, Hughes, Anderson, Hammann, Mustin had one bank removed). The last built were suspended and modified, then completed with two quad mounts on the centerline. They all carried the Mark 15 torpedoes.

Its the torpedo change that often trigerred the removal of the N°3 5-inch gun, but was kept for some extra time most cases. There was no longer talks of a "scissors launch" with the past destroyers, a theoretical play with modifiting the torpoedo gear setting to make them converge on a target forward. It was back to a more conventional approach.

The Mark 15 torpedo was the new WW2 standard torpedo, very similar to the Mark 14 but longer, heavier with greater range settings, larger warhead. Hoiwever, from the same NAS Newport from 1938 it also shared the same Mark 6 exploder usually causing duds. In some case, Mark 14 torpedoes even made full circles after launch, giving the chills to submarine commanders... The latter raised the alarm but it took 20 months to fix the torpedoes, during which the US kill rate was weak. When it was fixed and the new torpedoes sent to the frontline, by 1943 the situation had changed already and surface combat was rare and far between so this was not such an issue. In between, destroyers commander had taken the matter in their own hands and forcibly removed the serial exploder for an older contact one when available. The Sims class did had some occasions of torpedo fights in the Pacific, with mixed results (see later).


USS Sims in 1942 (src unknown - the blueprints)

Anti-Aircraft

20mm Oerlikon mount on USS Hogatt Bay

Initially in 1940 this consisted only in four single .50 caliber machine guns (12.7 mm), located on the superstructre amidships. This sounds adequate at the time, but was ludicrously unsufficient in 1941 and revised. In 1941 it was decided to remove the two heavy machine guns for eight autocannons, a mix of 40 mm Bofors and 20 mm Oerlikon guns. Thus upgrade was done over 18 months after Pearl Harbor, so still oinging in 1943. Four 40 mm in two twin mounts, four single 20 mm guns seems to be the favourite configuration. The twin mounts were located in place of the N°3 DP gun. In 1945, the kamikaze threat saw for USS Mustin, Morris, and Russell the full removal of their torpedo tubes for four additional 40 mm guns, eight in four twin mounts while the single were replaced by twin 20 mm, however not or partly completed.

ASW

Initially they had just the two classic depth charge racks aft (5 DCs each), 10 total, 10 reserve. In the summer of 1941 the N°3 5-in/38 127/38 wazs removed for the addition of four extra Cal.05 Browning HMGs and one depth charge thrower ("Y"-gun), with 38 depth charges total.Tne Y-Gun was often removed in 1942 and instead four DCTs ("K"-gun) were adeed aft in place, with 58 depht charges in all. But this varied over time. By 1945, DD410, 411, 419 had in additon to their four main guns two twin 40mm/60 Mk 1 Bofors, four single 20mm/70 Mk 10, two quad 533 TT, four DCT, and two DCR with the same 59 grenades.

Fire Control and Sensors

Shortly after the start of the war, they received the new Mk 37 fire control system assisted by a ballistic computer installed in a dedicated room of the bridge. A Mk 12.22 radar was installed atop. The Sims class started the war without radars. However from 1942 to 1944 when possible they were fitted with the SC, SG, Mk 4 or Mk 12.22 radars. One was for aerial warning (SC, SG) the others for the fire control. The Sims class were also among the last to receive the new QCE sonar instead of hydrophones, in 1945.

In many ways, the Sims were the draft of the next wartime Clemson/Gleaves. They gave full satisfaction during the war although four were lost in action: USS Sims, Hamann and O’Brien, Walke in 1942, and USS Buck in 1943. Ultimately they cumulated 91 battles stars.

Commissioned on 11 August 1939 (Arnold E. True) USS Hammann made her shakedown off the East Coast and spent the enewt two years training on both coasts. On 10 June 1939, she voided collision with USS Warrington with King George VI and Queen Elizabeth aboard (royal tour of the United States). It was claimed she reached a maximum speed of 40 knots durng a demonstration, then had her turbines in full reverse, stopping in 58 seconds, and then sailed in reverse at 20 knots. By December 1941, she was par tof the North Atlantic Patrol off Reykjavík. She ws in Norfolk on 17 December to resupply and left for Charleston, met USS New Mexico and SS President Hayes to Panama Canal and San Diego, then San Francisco. On 22 January 1942 she was in Pearl Harbor, joined TF 17. After training maneuvers off New Caledonia in March 1942 she sails for the Coral Sea, screening USS Lexington until back to Tongatapu on 20 April. She took part on the 27 April air raid on Tulagi.

On 4 May, USS Hammann rescued two fighter pilots downed on Guadalcanal and returned to Lexington. A the Battle of the Coral Sea she screened the carriers and downed at least two Japanese torpedo planes and tried later on dive bombers appeared. She had a near miss, 200 yards of her starboard bow. Lexington was later crippled and she assisted her with USS Anderson, rescuing 500 men on 8 May.

She was also present at the Battle of Midway, her last. On 30 May after a short run to Pearl Harbor she was back in escort on 4 June of USS Yorktown, and assisted many kills. She picked up survivors of Yorktow including Captain Buckmaster. The carrier was still afloat and repaired on 6 June until sunk by I-168. Of the spread, one on the fourth hit Hamman amidships, breaking her in half. She sank, bow first in four minutes, followed by a violent underwater explosion and she lost 80. Survivors were picked by Benham and Balch. Commander Arnold True was later awarded the Navy Cross, Navy Distinguished Service Medal and the ship two battle stars.
USS after commission and shakedown, then basic training, gunnery training, joined the Atlantic Fleet and a neutrality patrol time in the western Atlantic. By December 1941 she was being overhauled at Boston Navy Yard, which was rushed over to sail out the following day to escorting USS Idaho and Mississippi and completed this overhaul in Charleston on 3 January 1942. Then she crossed on orders the Panama Canal on the 20th reaching Pearl Harbor on 17 February and started escorting convoys between Hawaii and San Francisco, until 3 April, then to and from Samoa on 24 May. Later for reinforcements to Midway and she was back on 5 June to depart after with TF 17 looking after survivors of the battle of Midway. Next she started 2 months of training and patrols and returned with TF 17 on 17 August (USS Hornet group) to Guadalcanal as she launched strikes on Buin, Faisi, and Tonolai. Next she was present at the Battle of the Santa Cruz Islands on 26 October, rescued 337 survivors of the carrier and finishing the hull withtorpedoes. She claimed however five enemy aircraft in defense of her.

Next followed a period of convoys Nouméa-Espiritu Santo. By 11 November she joined TF 16 and took part in the Naval Battle of Guadalcanal. On 25 December she shelled positions on Guadalcanal. By February 1943 she did the same, then escorts until 14 April 1943 and back to Pearl Harbor. Next she was sent to take part in the Aleutian Campaigns, first at Adak, then Attu and shelling Kiska. After occupation of Kiska on 15 August, she headed for an OVL at Mare Island Naval, and back to Pearl Harbor on 31 October 1943.

Next she fought in the Central Pacific until October 1944 (assault on Makin, Marshall Campaign (Wotje, Kwajalein, Eniwetok) and back to Pearl Harbor on 3 March 1944. Escorting part of TF 58 (their fleet oilers) she assisted to strikes on Palau, Yap, Woleai, Ulithi (Carolines). In April she screened carriers during the assault on New Guinea (Aitape, Hollandia, Wakde) and rampaged IJN positions from Noemfoor to Biak.

Next was the Philippines campaing from October 1944 to February 1945. The assault on Morotai, and invasion of Leyte.
