The Curtiss SB2C Helldiver was a carrier-based dive bomber aircraft produced for the United States Navy during World War II. It replaced the Douglas SBD Dauntless in US Navy service. Despite its size, the SB2C was much faster than the SBD it replaced. Crew nicknames for the aircraft included the Big-Tailed Beast (or just the derogatory Beast), Two-Cee and Son-of-a-Bitch 2nd Class (after its designation and partly because of its reputation for having difficult handling characteristics).

Although production problems persisted throughout its combat service, pilots soon changed their minds about the potency of the Helldiver.

Delays marred its production. Built for the USAAF as the A-25 Shrike, by the time it was delivered it was no longer required. Substantial orders by the British Royal Navy and the Royal Australian Air Force were both cancelled due to the poor handling of the aircraft.

Design and development

The Helldiver was developed to replace the Douglas SBD Dauntless; it was a much larger aircraft able to operate from the latest aircraft carriers of the time and carry a considerable array of armament and featured an internal bomb bay that reduced drag when carrying heavy ordnance. Saddled with demanding requirements set forth by both the U.S. Marines and United States Army Air Forces, the manufacturer incorporated features of a "multi-role" aircraft into the design.

The Model XSB2C-1 prototype initially suffered teething problems connected to its R-2600 engine and 3-bladed propeller; further concerns included structural weaknesses, poor handling, directional instability and bad stall characteristics. The first prototype flew in December 1940. After the prototype crashed in February 1941, Curtiss was asked to rebuild it with revised structures and shapes. This second prototype version was also lost when in December 1941 the Helldiver pulled out of a dive and the starboard wing and tailplane failed catastrophically.

Large-scale production had already been ordered on 29 November 1940, but a large number of modifications were specified for the production model. The size of the fin and rudder was enlarged, fuel capacity was increased, self-sealing fuel tanks added and the fixed armament was doubled to four 0.50 in (12.7 mm) machine guns in the wings, compared with the prototype's two cowling guns. The SB2C-2 was built with larger fuel tanks, improving its range considerably.

The program suffered so many delays that the Grumman TBF Avenger entered service before the Helldiver, even though the Avenger had begun its development two years later. Nevertheless, production tempo accelerated with production at Columbus, Ohio and two Canadian factories: Fairchild Aircraft Ltd. (Canada) which produced a total of 300 (under the designations XSBF-l, SBF-l, SBF-3 and SBF-4E) and Canadian Car and Foundry which built 894 (designated SBW-l, SBW-3, SBW-4, SBW-4E and SBW-5), these models being respectively equivalent to their Curtiss-built counterparts. A total of 7,140 SB2Cs were produced in World War II.

Operational history

The U.S. Navy would not accept the SB2C until 880 modifications to the design and the changes on the production line had been made, delaying the Curtiss Helldiver's combat debut until 11 November 1943 with squadron VB-17 on the USS Bunker Hill, when they attacked the Japanese-held port of Rabaul on the island of New Britain, north of Papua New Guinea. Even though the Helldiver had entered U.S. Navy service, it still had such structural problems that the aircraft crews were forbidden to dive bomb (one of its main tasks) in clean configuration. The SB2C-1 could deploy slats mechanically linked with undercarriage actuation extended from the outer third of the wing leading edge to aid lateral control at low speeds. The early prognosis of the "Beast" was unfavourable as it was strongly disliked by aircrews because it was much bigger and heavier than the SBD it replaced.

In the first Battle of the Philippine Sea, 45 Helldivers were lost because they ran out of fuel on the return to their carriers.

The litany of faults that the Helldiver bore included the fact that it was underpowered, had a shorter range than the SBD, was equipped with an unreliable electrical system and was often poorly manufactured. The Curtis-Electric propeller and the complex hydraulic system had frequent maintenance problems.

The problems were largely solved by the time the SB2C-4 made its appearance. The aircrew eventually began to appreciate the aircraft's ability to keep up with escort fighters, to easily carry a heavier bomb load, and to sortie over a longer distance. The Helldivers would participate in battles over Marianas, Leyte (partly responsible for sinking the Musashi), Taiwan, and Okinawa (in the sinking of the Yamato).

An oddity of the SB2Cs with 1942 to 1943-style tricolor camouflage was that the undersides of the outer wing panels carried dark topside camouflage because the undersurfaces were visible from above when the wings were folded.

In operational experience it was found that the U.S. Navy's F6F and F4U fighters were able to carry just as heavy a bomb load and were far more able to take care of themselves against enemy fighters once their offensive armament had been discharged. The advent of air to ground rockets allowed the attack of ship and shore based targets without the stress and hence weight/performance issues that dive bombers had to endure. All this meant that the SB2C was the last purpose built dive bomber.

Postwar, surplus aircraft were sold to the navies of France, Italy, Greece, Portugal and Thailand.

Army service

Built at Curtiss' St. Louis plant, 900 aircraft were ordered by the USAAF under the designation A-25A Shrike. The first 10 aircraft had folding wings, while the remainder of the production order deleted this unneeded feature. Many other changes distinguished the A-25A including larger main wheels, a pneumatic tail wheel, ring and bead gunsight, longer exhaust stubs and other Army specified radio equipment. By later 1943 when the A-25A was being introduced, the USAAF no longer had a role for the dive bomber. After offering the Shrike to Australia, only 10 were accepted before the Royal Australian Air Force rejected the remainder of the order, forcing the USAAF to send 410 to the U.S. Marines. The A-25As were converted to SB2C-1 standard but the Marine SB2C-1 variant never saw combat, being used primarily as trainers. The remaining A-25As were similarly employed as trainers and target tugs.

British service

A comparable scenario accompanied the Helldiver's service with the British. A total of 26 aircraft, out of 450 ordered, were delivered to the Royal Navy's Fleet Air Arm, where they were known as the Helldiver I. After unsatisfactory tests that pinpointed "appalling handling", none of the British Helldivers were used in action.

Accidents and incidents

On 25 March 2010, the Oregon State Police, Tillamook County Sheriff's Office and the United Sates Navy announced that during a logging operation near Rockaway Beach, Oregon, the wreck of an SB2C Helldiver was located. Initial responders believe there are possible human remains at the scene.

An SB2C-1C Helldiver that was ditched in Maalaea Bay off South Maui in August 1944 was discovered in January 2010 by Brad Varney, owner of B&B Scuba. The Helldiver is covered in coral and is missing its tail section. The aircraft experienced problems with its empennage after dive bombing maneuvers which forced pilot Lieutenant William Dill to ditch in Maalaea Bay. It lies in 50 ft of water facing east. The site, which is protected under state and federal law, is in the process of being marked with a plaque by the US Navy. A mooring may be installed at a later point in time to facilitate dives on the site.

Survivors

One SB2C Helldiver is still flying. Owned by the Commemorative Air Force, this late-production SB2C-5 (BuNo. 83589) built in 1945 is based in Graham, Texas and makes frequent air show appearances. In 1982, it experienced engine failure and a hard emergency landing that caused extensive damage; volunteers of the CAF put in thousands of hours and spent in excess of $200,000 to restore the aircraft to flying condition once more.

Other surviving airframes include

A-25A "Shrike" (s/n 42-80449) is located at the National Museum of the United States Air Force in Dayton, Ohio.
SB2C-5, BuNo. 83479 at the National Air and Space Museum
SB2C-3, BuNo. 19075 at the Yanks Air Museum, Chino, California
SB2C-5, BuNo. 83321 at the Hellenic Air Force Museum, Decelea Air Base, Greece
SB2C-5, BuNo. 83410 at the Royal Thai Air Force Museum, Don Muang AB, Bangkok

SB2C-4, BuNo. 19866 submerged in Lower Otay Reservoir, San Diego, California may soon be salvaged.
