Future development study by the armor committee of 1946

This study (dated 1946-07-02) presents what the armor committee of 1946 thinks future Swedish tank developments should focus on, in light of foreign developments, current technical limitations, requirements and desires from the army headquarters and various other factors. The study is about 50 pages long plus seven appendices, not all of which are present here.

The committee finds that research should focus on:

  • raising the muzzle velocity of current anti-tank guns above 900 m/s
  • improving current AP rounds so that they don’t shatter at impact velocities over 900 m/s, possibly by using a core of a harder material
  • finding a way to make HEAT rounds work at high impact velocities
  • developing an effective protection against HEAT rounds
  • studying the actual damage effects of HEAT rounds

Further, it recommends that development should start on:
A) a tank, preferably no heavier than 25 tons, armed with either a 7,5 cm or a 10,5 cm gun, with a specific engine power of about 20 hp/ton and protected frontally against guns of up to 57 mm caliber at 400 meters.
B) a tank destroyer, no heavier than 30 tons, armed with either 10,5 cm kan m/34 or 10,5 cm lvkan m/42, with a specific engine power of about 17 hp/ton and frontal protection against guns of up to 7,5 cm caliber at 800 meters.

Finally, it also discusses re-use of older tanks, such as rebuilding strv m/41 into a TD with a 7,5 cm gun.

Memo regarding APCR

This memo (dated 1946-12-03) discusses a new and interesting ammunition technology, namely projectiles with a core of a brittle but very hard metal, such as tungsten carbide. In order to keep the high speed of the projectile, various technologies (such as conical guns and sub-caliber saboted rounds) are possible. The author recommends contracting Bofors to develop such ammunition for trials with the 75 mm pvkan m/43, and that some in-house trials with the 37 mm pvkan should also be conducted.
