FSX Grumman Avenger TBM-3W. The Eastern TBM-3W Avenger was an airborne early warning radar aircraft developed during the Second World War but that only entered service in May 1946. The TBM-3W joined the fleet in May 1946, and was soon paired with the TBM-3S in hunter-killer anti-submarine teams. The powerful radar in the -3W would be used to find a potential Soviet submarine, guiding the -3S onto its target. The -3W remained in service with the US fleet until the mid 1950. Gmax model, tested in FSX/FSX Acceleration/FS2004 Windows 7/8 by A.F. Scrub.
