This letter (dated 1952-09-27) from Bofors to KAFT describes a proposed construction program for a 105 mm L/67 rifled tank gun, fed by two 7-round autoloader drums and placed in a heavily armored turret intended to be mounted in a 35-ton tank currently being under development at KAFT (project EMIL, of course). The letter mentions that 12 and 15 cm L/40 smoothbore guns are also possible alternatives but no further details are provided. There’s a list of blueprints for these guns but they are (as usual) missing from the archives because apparently the bureaucrats at the time hated historians.

I’ve previously posted about project EMIL here; more specifically, a complete project summary with contents from various times during the project’s life. These 1951 documents however mark the very start of the project, suggesting that KAFT put six people to work for about a year in order to develop the project a loose idea to reasonably complete plans for a tank. There’s nothing new specs-wise here, just some project history.

Minutes of a meeting held at Bofors on May 30th and 31st 1951, regarding current projects. Most interestingly, a “new tank gun” is discussed, with some different alternatives presented.

This is a report of the then-current status of the EMIL project (also known as krv, kranvagn, project 6400, etc), dated 1952-10-15. Over the course of some hundred pages or so (although not all of the original pages seem to be in the archive I found it in) it covers in great detail what a tank like EMIL needs to do and why it needs to do it.

Note that this report was originally classified top secret (“of great importance for the security of the realm”); the reason it’s in an archive volume dated 1958 is because its classification status was reduced to “regular secret” at that point; top secret and regular secret archives are kept separately.
