Another aviation milestone today with the first flight of Jim Slattery's SB2C-1A Helldiver after restoration by Westpac in Colorado Springs. They were hoping to get her done in time to make the August 17-18 Pike's Peak Airshow and it looks like she'll be able to fly there publicly as well.

With her completion there are now three airworthy Helldivers in the world; Fagen's newly completed SB2C-5 the CAF's SB2C-5, and now Slattery's SB2C-1

Curtiss SB2C-5 Helldiver

The Helldiver was developed to replace the Douglas SBD Dauntless. It was a much larger aircraft, able to operate from the latest aircraft carriers and carry a considerable array of armament. It 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 development issues connected to its Wright R-2600 Twin Cyclone engine and three-bladed propeller; further concerns included structural weaknesses, poor handling, directional instability, and bad stall characteristics. In 1939, a student took a model of the new Curtiss XSB2C-1 to the MIT wind tunnel. Professor of Aeronautical Engineering Otto C. Koppen was quoted as saying, "if they build more than one of these, they are crazy". He was referring to controllability issues with the small vertical tail.

The first prototype made its maiden flight on 18 December 1940. It crashed on 8 February 1941 when its engine failed on approach, but Curtiss was asked to rebuild it. The fuselage was lengthened and a larger tail was fitted, while an autopilot was fitted to help the poor stability. The revised prototype flew again on 20 October 1941, but was destroyed when its wing failed during diving tests on 21 December 1941.

Large-scale production had already been ordered on 29 November 1940, but a large number of modifications were specified for the production model. Fin and rudder area were increased, fuel capacity was increased, self-sealing fuel tanks were 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-1 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 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 and equivalent models were produced in World War II.

Initially poor handling characteristics and late modifications caused lengthy delays to production and deployment, to the extent that it was investigated by the Truman Committee, which turned in a scathing report. This contributed to the decline of Curtiss as a company. Neither pilots nor aircraft carrier skippers seemed to like it. Nevertheless, the type was faster than the Dauntless, and by the end of the Pacific War, the Helldiver had become the main dive bomber and attack aircraft on USN carriers.

By the time a land-based variant, known as the A-25 Shrike, became available in late 1943, the Western Allied air forces had abandoned dedicated dive-bombers. A majority of A-25s delivered to the US Army Air Forces were transferred to the US Marine Corps, which used the type only in one side campaign and non-combat roles. The British Royal Navy and the Royal Australian Air Force also cancelled substantial orders, retaining only a few aircraft for research purposes.

Nicknames for the aircraft included "Big-Tailed Beast" or just "Beast", "Two-Cee", and "Son-of-a-Bitch 2nd Class"; the latter nickname was derived from the name SB2C and the aircraft's reputation for having difficult handling characteristics.

A hearty Bravo Zulu to the team at Fagen Fighters for the first flight of their SB2C-5 Helldiver. It's been a long time coming and now there's finally a second Helldiver back in the air to join the CAF one.

WestPac has nearly finished their SB2C restoration as well and they hope to get her airborne in time for the August airshow.
