The Sturmgewehr 45 (H) (abbreviated as St.G. 45 (H)), also known as Maschinenpistole 45 (abbreviated as M.P. 45), is a German prototype assault rifle developed in the mid 1940s.

Development

After the introduction of the St.G. 44 (then known as M.P. 43), efforts were undertaken to design a cheaper alternative filling the same role. Großfuß, Gustloff, Haenel, Mauser, Spreewerk, and Steyr all began work designing a simplified system. It is unknown whether the Waffenamt or by extension Wa Prüf 2 was involved in the procurement of a simplified alternative to the St.G. 44.

The development of an M.P. 45, also known as St.G. 45 (H), would begin in the latter half of 1944. The design would utilize the M.P. 43 as a base, and various design elements from the earlier M.Kb. 42 (H).

Manufacturing of the St.G. 45 (H) was done by hand for trial models, but engineering documentation for planned mass production have been found. Evaluation of the St.G. 45 (M) was likely underway, but the end of the war prevented any further development of the weapon.

Design

The St.G. 45 (H) is based on the St.G. 44, with many changes to simplify the weapon for mass production. The entire chassis is sheet metal, with a simplified pistol grip and stock. The handguard was redesigned, but information regarding its design has not been found.

The gas-operated system was similar to that of the St.G. 44, although inverted and with the gas piston and bolt carrying system located beneath the barrel. The direct-release firing system from the M.Kb. 42 (H) was used, along with its fire selector.

Variants

M.Kb. 42 (H) Trial series model from Haenel. Passed trials. M.Kb. 42 (W) Trial series model from Walther. Did not pass trails. M.P. 43/1 Early production model. St.G. 44 — M.P. 44 Primary production model. Domestic Derivatives M.G. 44 Vehicle machine gun model. St.G. 45 (H) Haenel derivative. (*) M.Kb. Gerät 06 Mauser derivative, cheaper. St.G. 45 (M) — M.Kb. Gerät 06 H Mauser derivative, half-locked.
