Curtiss SB2C Helldiver

The Curtiss SB2C Helldiver was an all-metal monoplane dive bomber with a radial engine and retractable landing gear operated by the US Navy, the US Marine Corp, and the USAAC as the A-25 Shrike.  Per reference [8] it took its first flight on 10 December 1940, and entered operational service in December 1942.  The SB2C was built in several variants, including the SBF series built by Fairchild Canada, the SBW series built by the Canadian Car & Foundry Compnay, and the A-25 which had fixed (non-folding) wings and no arrestor gear.  The primary variants analyzed at this website is the SB2C-5, built by Curtiss.
 During the war the SB2C/A-25 was used primarily by the US Navy, the US Marine Corps, and the USAAC.  Although they were also ordered by the Royal Air Force and Royal Australian Air Force for use, only small numbers were delivered to those services for evaluation during the war, with the majority of the outstanding orders cancelled as land based dive bombers were replaced by light bombers during the mid to late war periods.  Post WWII the SB2C was operated by the Greek Air Force and French Navy.

Per reference [8] a total of 7,140 SB2C/A-25 aircraft of all variants were procured.
