Doubt it. Super 40mm Bushmaster is an impressive round but it isn't 40mm Bofors.donald_of_tokyo wrote:Is MSI system capable of 3P rounds? Integration into Bushmaster 40mm cannon?? Not sure.
Ultimately, if there was a need to go to airburst then I'd hope we'd go to Super 40mm Bushmaster as even though 30mm airburst has been demo'd there is still the issue of space for a bursting charge in amongst the electronics. 40mm has enough space for the fuse and a worthwhile charge, 30mm's effect is going to be a whole lot lower than the calibre difference suggests.
I've no expectation that the RN will go down this route, as others have said it appears to be a case of 2 ammo feeds or 1 feed and Martlet canisters (not as a result of space, more likely weight, as having both would imbalance the mount). Saying that realistically you only need 1 nature anyway. Airburst is the perfect round to target UAS, helos or Fast Attack Craft. Even with a modern stabilised mount the number of rounds that do not impact a target if there is the slightest ship motion or non-cooperative target is huge...and damn the cost...if they're that close that you're using the ASCG you want to kill them and kill them fast.
I think its worth noting that there are simple solutions out there that could be useful to upgun some of the fleet and provide increased protection against threats that are only increasing. River Batch 2 with a Super 40mm DS40M with programmable airburst rounds and a 4 round Martlet/Starstreak launcher would be very capable of looking after herself for a comparatively small outlay.
