飛行機 SB2C ヘルダイバー 会社によって建てられた カーチス et que ses équipages ont surnommé «La bête» (The Beast) est un avion militaire qui a évolué durant la Seconde Guerre mondiale. L’usine カーチス ブリュースターと同様に、5月39日に米海軍から、米海軍空母に搭載された潜水爆撃機としてのダグラスSBDドーントレスの交換を提供する命令を受けた。プロトタイプは1940年12月18日に最初の試験飛行を行い、その後の数日間に事故で破壊されました。この事件は、元の草案に対する多数の変更によって遅延が悪化し、1942年6月よりも最初のシリアル飛行が生じたことを意味した。その最初の戦争任務は、日本占領下のラバウル島への攻撃中の1943年11月11日に行われたようです。

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” そして “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:
| 型 | 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.
