As I understand, the M621 single-barrel cannon is available for marine applications on small vessels, however, a CIWS against an incoming missile needs a very high rate of fire to be effective - which means a Gatling configuration. You mentioned 'against a torpedo' - that's an underwater weapon isn't it ? Perhaps you meant an anti-ship missile.
Thanks Hari Nair,
if the 9dB reduction in blade noise can be translated to reduced distance between insertion and targets, wouldn't that help? maybe its all dicey based on the surroundings like in hills vs. plains
on the CIWS, Here is a scenario,
IN has plans to carry helis on every one of its ships, the heli could be a 'NRURAV'
An IN ship detects the presence of a sub with its Sonar and sends the heli armed with an onboard torpedo to engage it
now the sub fires its own torpedo against the ship before it gets intercepted
IN ship is tracking this torpedo and it communicates with the heli effectively treating the chopper as a flying CIWS with the command and guidance being on a wireless path. The heli engages with its onboard gatling gun which can penetrate the water surface upto 10m in depth. The whole engagement is controlled by the ship's BMS and the heli is left on auto-pilot
the assumption here is the torpedo is closer to the water surface within 1-2 km of the ship
Now the LCH by design carries a gun, even if it doesn't go onto a Naval platform, they could apply the learning's to the naval choppers, the transition from a simple gun to an accurate gatling gun is a question of improving the fidelity of the system and perhaps the LCH can prove it for NRURAV
this was all before I learnt Adm. Gorshkov carries a anti-torpedo CIWS but smaller vessels can benefit if feasible
