    I've been interested in armaments available to modern aircraft and I can't figure whether anyone still builds the old H.S.404 or an equivalent old fashioned 20mm cannon. Failing that, is a 20mm chaingun produced for the military market?

    In the west, the ADEN cannon is still utilized in 30mm (British Harrier) and I think 25mm (USMC Harrier).

    ADEN cannon - Wikipedia, the free encyclopedia

    I am not aware of a 20mm chain gun. I've seen it in 25mm (shipborne and AFVs) and 30mm (Apache). I think that some exist in rifle caliber for coax mounts too.

    I believe the L39 has the ability to carry two 23 mm cannon, non rotary.

    South Africa manufactures the Vektor GA1 in 20x82 for aircraft use amongst other things. Its pretty much the MG151/20 brought up to modern standards.

    Well, to be complete technically honest the M61A1 fits the category since is not a revolver gun but a rotating gatling gun.
    But I guess you mean a reciprocating cannon.
    2 examples come to my mind. The french M621 and the Rehimetal RH 202 , the first use the 20x102mm case and the german the 20x139mm, both fire at 1000 rpm.

    RH 202

    As curiosity the Argentine air force still use the HS 804 ( 20x110mm at 800rpm) and the Colt MK 12 ( 20x110 U.S.N at 1100 rpm)
