Drawing of the L-3 design. |
Although the M41 Bulldog entered production in 1951, it did not completely fulfill the requirements for a light tank as specified by the Army Field Forces. It was thus regarded as an interm vehicle, while the Army sought designs for a more lightweight tank, that was both inexpensive and had a longer cruising range. In an effort to meet these new requirements, numerous light tank concepts were proposed at the first of what would be many Questionmark Conferences, where tank designers and tank users could meet to determine the future of armored vehicle development.

Wooden model of the L-5 design. |
Detroit Arsenal submitted six design proposals for a new light tank concept. The third of these expanded the turret ring from the previous two designs to 85 inches and was powered by the AX-660 engine. The fifth design mounted the more powerful 105 mm Gun T140, but was otherwise identical. The two tanks were expected to weigh 22 tons and 26 tons, respectively.
This vehicle I'm proposing, the L-3/5, is simply a combination of these two designs.
Guns: 90 mm Gun T139; 105 mm Gun T140
Engines: Continental AO-536 (250 hp); GMC AX-660 (430 hp)
Turrets (Turret Armor (mm)): L-3 (25/25/25); L-5 (25/25/25)
Suspensions/Alternate Hulls, Total Weight (metric tons): L-3 (19.96); L-5 (23.59)
Hull Armor (mm): 25/25/13
Top Speed: ?? km/h
Crew: 4 (Driver; Gunner; Loader; Commander/Radio)
Parent: L-1/2
Children: L-6
