The French navy received 40 V-156F dive-bombers in 1939. They suffered heavy losses during operations against the German army in May 1940. One squadron saw action against the Italians in June. Following the fall of France a follow-on order for 50 aircraft was taken over by Britain. Modified to V-156B-1 Chesapeake I standard, they were judged underpowered and used for second-line duties. It is reported that AL936 was written off while serving with No 811 Sqn which only operated the 'Cheesecake' for a few months in 1941. A Douglas Boston is also seen. Photo from: Flight

Prototype of a long-range floatplane version of the SB2U. It was converted back to an SB2U-1. The designation SB2U-3 was reused for an upgraded version of the carrier-based dive bomber. Photo by: Rudy Arnold / Smithsonian Institution

The pilot's name on the plane is Aviation Cadet George H. Carter. The normal complement of a Navy squadron in 1939 was 18 planes, so this is a rare photo.

1939-built Vought Vindicator dive bomber - the last survivor of the type. Ditched in Lake Michigan on 21 June 1943 during a training flight and recovered postwar. Restored in the early WW2 markings of VB-2 Squadron USN.

This is the only SB2U extant and was delivered in July 1939, serving in patrol roles until it was transferred to Carrier Qualification Training Unit, Glenview NAS, IL. and assigned to the USS Wolverine (IX-64). It crashed a month later and sunk to the bottom of Lake Michigan, where it stayed until recovery in 1990. After restoration it is now on display at the National Naval Aviation Museum.
