Douglas TBD Devastator

The prototype of the Devastator torpedo bomber flew for the first time on 15 April 1935. It was the first monoplane selected for aircraft-carrier operations, the first of 129 ordered by the US Navy entering service in 1937. Armed with only one forward-firing and one rear-mounted machine-gun (plus a 533mm torpedo or 450kg bomb), it was. very vulnerable to enemy attack: heavy losses were suffered in action against the Japanese during the early part of World War II, especially during the Battle of the Coral Sea when the type operated from USS Lexington and Yorktown, the former being sunk but only after Devastator and Dauntless bombers had sunk the Japanese carrier Shoho and severely damaged Shokaku. The Battle of Midway, fought between 4 and 7 June 1942, was the Devastator's last major action: it was relegated to non-combat duties after suffering heavy losses during the battle.

Paul is correct, the clamshell window was for use when delivering a torpedo attack. For your information, there is a group, working with the USN, that intends to rasie a TBD-1 out of the waters of a lagoon at Jaluit Atoll. They are raising money for the effort. Check out the website at www.tighar.org.

I believe those clamshells were for opening the window
so the assist pilot/bombadier could use the norden bomb sight

Can you tell me on the TBD Devastator as to what the small clam shell underneath the engine is for? It looks too small for bombs. The model airplane I have don't tell what it was for and I'm not sure if it's for a small bombs or for the pilot to observe his torpedo run. Thanks. Ray

Do you have any comments about this aircraft ?

FACTS AND FIGURES

© For the first time in a Navy bomber rhe TBD featured an enclosed cockpit and all-meta construction. The corrugated wing surfaces contributed to strength bur increased drag.

© Useless torpedoes, weak defensive armament and a lack of self-sealing fuel tanks contributed to the Devastator's failure in combat.

© The folding wings were a novel feature and in the prewar days sometimes the wing locks were forgotten, leading to a plunge into the sea on take-off.
