Design and development
The original design, the [Vous devez être inscrit et connecté pour voir ce lien] of 1944, was to be a twin-engined aircraft with a 3,600 lb (1,633 kg) warload and a range of 3,700 mi (5,950 km).
This was considered to be too large for practical use from an [Vous devez être inscrit et connecté pour voir ce lien], and was canceled in 1945, replaced by a modified [Vous devez être inscrit et connecté pour voir ce lien], the [Vous devez être inscrit et connecté pour voir ce lien].

However, another alternative, the internally-developed Model G-70, was selected instead, and given the Navy designation XTB3F.
This was designed as mixed-power aircraft, with a [Vous devez être inscrit et connecté pour voir ce lien] radial engine in the nose and a [Vous devez être inscrit et connecté pour voir ce lien] turbojet in the tail.
This was found to be unsuitable and the jet engine was removed without ever having been used in flight.

On 24 December 1945, the Navy changed the role of the aircraft from torpedo-bomber to anti-submarine warfare.
All the required equipment could not be fitted into a single aircraft, consequently two variants would be produced, one as a "hunter" and another as a "killer."
The "hunter" aircraft would not carry any armament, but instead two additional crew members and a ventral radome for [Vous devez être inscrit et connecté pour voir ce lien] search [Vous devez être inscrit et connecté pour voir ce lien].
This aircraft, the XTB3F-1S, first flew in November 1948.

The Guardian was used as a landbased and carrier ASW aircraft by the US Naval Air Reserve during the period just prior to its replacement by the Grumman S2F Tracker and in conjunction with the Lockheed P2V (P-2) Neptune.
It was used extensively on the East Coast for ASW Patrol and training for the Naval Reserve, Willow Grove NAS being one of the main training bases for the central East Coast area.
