Re: Royal Navy Gunnery Discussion

The 76mm gun in the old USN FFG 7s did not have a good reputation for reliability and the US DoD DOT&E reports on accuracy of the 57 on the LCS left a lot to be desired, it was only in last couple of years it shown improvement. The 76 shell is marginal for NGFS as low in weight and short range 1...

Re: Type 31 General Purpose Frigate [News Only]

The Type 31 Thales Nederland AESA radar referred to as NS110, though on Thales website only find NS100, googled - The number of transmitter modules (building block modules of S-band GaN silicon solid state TRMs) in the radar antenna can be scaled to the customer's requirements.

Re: Royal Navy Gunnery Discussion

why not Starstreak for CIWS Who is going to guide it, from an unmanned mount? I'm unclear if Thales already has a remote control for missile, if not expect they would be delighted if RN funded them to add remote control so as to operate from CIC (would note that the pics have seen of the Aselsan 4 ...

Re: Royal Navy Gunnery Discussion

Correction, The DARPA 57 Madfires in R&D, as yet not adopted by USN, is rocket powered to give longer range, the trade-off will be smaller fragmentation warhead reducing its Pk. MAD-FIRES is a hit-to-kill interceptor. Thanks for info that the 57mm Madfires is a HTK missile/projectile, pure spec...

Re: 76mm Oto Melara

Why go with 40mm over 30mm+LMM? The newest 40 from Bofors, with appropriate rounds, is also a CIWS; neither in the other combo gives you that. - xav will, no doubt, soon inform us what the MN chose for their supply ships. One type needs to cover all needs (to avoid the need of having an escort at a...

Re: Type 45 Destroyer (Daring Class) (RN) [News Only]

So on average each T45 deployed 80 days/22% of year, a good, bad or very indifferent record for a fleet of six ships? Understand USN Burkes ~135 days whose ships date back to the 90's and with the new FFG(X) USN aiming to more than double that figure. No reason given why MoD did not report differen...

but could it be a good move for the RN to move to a mix of 76 mm and 40 mm for both the T-45 and the T-31 and do away with the 114 mm the 30 mm and Phalanx on these ships to have a armament like so I've said it before but the Mk8 is a dinosaur - smart ammunition is the future and the Mk8 is never g...

Even their Light Cruisers by the end of the war had 6 dual 5 inch DP guns, 4 quadrup...
