目前国际出现一种力求使航炮发展成口径较小而威力更大以及其他性能指标更佳的趋势。在这种形势下,英国皇家军械厂发展了“阿登”25毫米航炮。“阿登”25毫米航炮虽口径比原“阿登”30毫米航炮小5毫米,但其弹丸威力却是它的3倍,初速从原“阿登”30毫米的795米/秒提高到1050米/秒,射速 At present, there is a trend in the world that seeks to develop the artillery gun into a caliber that is smaller and more powerful, as well as other performance indicators. Under such circumstances, the British Royal Ordnance Factory developed the “Arden” 25-mm cannon. Although the caliber of the Arden 25mm gun was 5mm smaller than the original Arden 30mm gun, its projectile power was three times its muzzle velocity, increasing from an initial Arden of 30mm at 795m / s To 1050 m / s, the rate of fire
