Het vliegtuig SB2C Helldiver gebouwd door de firma Curtiss et que ses équipages ont surnommé «La bête» (The Beast) est un avion militaire qui a évolué durant la Seconde Guerre mondiale. L’usine Curtiss evenals die van Brewster ontving een order van de Amerikaanse marine in mei 39 om te voorzien in de vervanging van Douglas SBD Dauntless als een duikbommenwerper ingescheept op vliegdekschepen van de Amerikaanse marine. Het prototype maakte zijn eerste testvlucht op 18 december 1940 voordat het in de dagen daarna bij een ongeluk werd vernietigd. Dit incident zorgde ervoor dat de vertraging zich opstapelde, verergerd door talrijke wijzigingen in vergelijking met het oorspronkelijke project, wat resulteerde in een eerste productievlucht pas in juni 1942. Zijn eerste oorlogsmissie werd blijkbaar uitgevoerd op 11 november 1943 tijdens de aanval gericht op het bombarderen van het door de Japanners bezette eiland Rabaul.

The Curtiss SB2C Helldiver was a single-engine, two-seat carrier-based dive bomber developed for the United States Navy during World War II. It was designed to replace the highly successful Douglas SBD Dauntless, offering greater speed, range, and ordnance capacity.
While designed to be a significant leap forward, the Helldiver suffered from numerous technical and handling problems during its early development and service introduction. Its challenging low-speed handling characteristics and large size earned it the notorious nicknames, such as “The Beast” En “Son-of-a-Bitch 2nd Class” (a play on its SB2C designation). Despite its poor reputation among pilots, extensive modifications eventually made it the principal U.S. Navy dive bomber in the Pacific theater, credited with sinking more Japanese naval tonnage than any other type.
The SB2C-5 Variant
The SB2C-5 was the final and most refined production version of the Helldiver series, featuring numerous improvements based on combat experience:
Armament and Payload
The Helldiver was built to carry a heavy and varied load of weapons, utilizing an internal bomb bay to maintain aerodynamic efficiency during flight:
| Type | Details |
|---|---|
| Fixed Guns | 2 × 20 mm AN/M2 cannons mounted in the wings. |
| Defensive Guns | 2 × 7.62 mm (.30 cal) machine guns in a flexible dorsal mount for the rear gunner. |
| Internal Payload | Up to 2,000 lbs (907 kg) of bombs, or 1 × Mark 13-2 torpedo. |
| External Payload | Up to 8 × High Velocity Aircraft Rockets (HVAR) or additional bombs on underwing hardpoints. |
Key Design Characteristics
- Dive Brakes: Featured large, distinctive perforated (or “Swiss cheese”) split flaps that extended to slow the aircraft and prevent structural failure during steep, high-speed dives, ensuring accurate bomb release.
- Internal Bomb Bay: Allowed the Helldiver to carry its primary ordnance load completely within the fuselage, reducing drag compared to carrying bombs externally.
- Increased Fuel: The SB2C-5 variant had an increased fuel capacity, boosting its operational range.
- Canopy: Later models, including the -5, often featured a frameless canopy for the pilot to improve visibility.
The arrival of air-to-ground rockets and the development of more versatile fighter-bombers ultimately made the specialized dive bomber obsolete, cementing the Curtiss Helldiver as the last of its kind in U.S. Navy service.
