Galeria de Fotos em um Curtiss SB2C-5 Helldiver, The Curtiss SB2C Helldiver surnommé « The beast » (La bête) par ses équipages est un avion militaire de la Seconde Guerre mondiale. L’usine Curtiss recebeu como Brewster uma ordem da Marinha dos EUA em maio de 1939 para substituir o Douglas SBD Dauntless como um bombardeiro de mergulho em porta-aviões dos EUA. O protótipo voou pela primeira vez em 18 de dezembro de 1940, mas foi destruído em um acidente alguns dias depois. Este incidente, bem como as numerosas modificações (aumento da capacidade de transporte de combustível, tanques de carona, reforço do armamento a bordo, aumento da área de superfície da deriva e leme) causou um atraso significativo e embora a primeira cópia da série tenha voado em junho de 1942, a primeira missão de guerra não ocorreu até 11 de novembro de 1943 com o bombardeio da Ilha Rabaul.

O Curtiss SB2C Helldiver was the U.S. Navy’s principal carrier-based dive bomber during the latter half of World War II. Intended to replace the venerable SBD Dauntless, the SB2C was a larger, faster, and much more powerful aircraft. The SB2C-5 was the final production variant, featuring key improvements that addressed many of the earlier model’s notorious handling issues, earning it a grudging respect despite its difficult reputation.


Key Specifications (SB2C-5 Variant)

  • Papel: Carrier-based Scout Bomber / Dive Bomber.
  • Power Plant: One Wright R-2600-20 ‘Twin Cyclone’ radial engine, delivering 1,900 hp.
  • Crew: Two (Pilot and Radio Operator/Gunner).
  • Max Speed: Approximately 295 mph (475 km/h).
  • Armament (Fixed): Dois 20 mm M2 cannons in the wings.
  • Armament (Flexible): Two .30 cal M1919 Browning machine guns in the rear cockpit.
  • Ordnance: Até 2,000 lbs (907 kg) of bombs in an internal bomb bay or one Mark 13 torpedo (partially external), plus HVAR rockets or bombs on underwing hardpoints.
  • Key Improvement: The -5 variant notably featured aumento da capacidade de combustível, extending its operational range.

Design and Operational History

The Helldiver’s development was protracted and plagued with issues, leading to its unflattering nicknames like the “Beast” or “Son of a Bitch Second Class.” The Navy’s requirement for a large aircraft with a substantial internal payload that could still fit two-abreast on carrier elevators forced Curtiss into a short-coupled design, which initially resulted in poor stability and difficult low-speed handling, especially during carrier landings.

However, once introduced, the later variants (like the SB2C-3, -4, and -5) became effective warplanes. They played a critical role in the major battles of the Pacific, including the Marianas, Leyte Gulf, and Okinawa, where their heavy bomb load and accurate diving attack contributed to the sinking of numerous Japanese warships.

Historical Impact: By the end of WWII, the Curtiss SB2C Helldiver was responsible for sinking more Japanese shipping tonnage via dive bombing than any other Allied aircraft type. It was also the last dedicated dive bomber produced for the U.S. Navy, as the role was increasingly taken over by more versatile fighter-bombers equipped with rockets and bombs.
