    23mm APDSFS ?



    Who knows what kind of guns for this round? and what country was it created?

    presumably this is for 23mm guns VYa

    Well, it won't be for the VYa which was a WW2 aircraft gun, it will be for the 2A7 or 2A14 as used in the ZU/ZSU/Shilka AA gun systems and in some light AFVs like the Bulgarian BP-23. Presumably this loading was intended for the latter. I am aware of APDS and FAPDS loadings in this calibre, but not APFSDS.

    In 1991, after the impressive show of the Exocet seaskimmer in the Falklands war, all navy countries were looking for a near in defence against this threat. In Germany a 27mm APDSFS round was developed for the 27mm aircraft gun (1700 rounds/minute) as used on Tornado and Alpha jets. 4 of these guns were mounted in the old 40mm Bofors turrets on ships. Some time ago a new 25mm improved version was put on the market. It only seems normal that after 20 years other countries come up with designs for their caliber guns.

    The quad-27mm shipboard mounting was the Mauser Drakon; it was never adopted. The same gun fitted in a single-gun remotely-controlled mounting designated MLG 27 has been bought by the German and other navies, but that's as a general-purpose light cannon rather than for the anti-missile role.

    I'm not sure what you mean by "25mm improved version". No-one uses APFSDS in the shipborne anti-missile role. On the other hand, APFSDS in the 25x137 NATO calibre is used in various light AFV guns.

    Tony, would the OAL of the shown projectile not exclude any of the guns we know?
    Also there is no portion below the driving band section which would allow the projectile to be fixed to a case. To me it looks more like a projectile for single loading test barrels.
