Re: Current & Future Escorts - General Discussion

On the assets to be forward deployed. I see no problem sending T31e. Any of the Leander, Arrowhead 140, and MEKOA200 (?) is a perfect match for, at least some of those tasks. 1: Against China or Russia, its modest fighting power is not a problem, even a T45 or a T26 is "nothing" in their v...

If true, very sad and also think it is a bad move. Another big damage for recruiting youth and getting public understanding.

Re: Current & Future Amphibious Capability - General Discussion

The 3rd flat top must not, and will not have (because of lack of F35b), any F35 to be carried. No need, RN has two CVF, that is enough. The point of LPH is to keep the air asset far beyond the horizon. A ship with well dock must be located near the shore, which is totally not needed for LPH. As PoW ...

Re: Current & Future Amphibious Capability - General Discussion

...What I've read is that a mini-refit in dock every 7 years has been planned for, exactly to avert such an availability crisis. Hoping it goes well. And I agree it may work “for a while”. But we all remember T45’s ambitious plan to keep 5 out of 6 T45 “ready” which quickly failed. We will see it a...

Re: River Class (OPV) (RN)

"USVs" and "CAPTAS-1" both are applicable to Type-31 frigates . As can be easily imagined, adding (even) CAPTAS-1 to T31 will be very promising. But, as ASW-USV can be carried on 5 River B2, 5 T31e, 8 T26 (and even 3 Bays, 2 CVFs, 8-10 (?) MHCs (or 2 Echo)), it is more worth tryi...

River is 13.6m wide and 90m long, so it can go anywhere. Israeli SeaGull USV is good that they worked in sea state 5-6, but it is not clear if it is also true for ASW (I understand it was on MCM). This two things are both promising = good things. But, I agree USV option will be "more advanced&q...

Compact VDS/TASS examples: As the ship noise is not strong above ~1 kHz, while those VDS/TASS in active mode is using ~2 kHz (CAPTAS-1) or 22-29 kHz (ST2400), maybe "River B2 noisy" issue will not be a big problem. Thales CAPTAS-1 (<2 kHz) With Blue Watcher (hull-mounted FLASH), it is spec...

Throw height is the apogee of the soft launch sequence. From the video's posted it seems to be about 30m (cant tell exactly from the naval angles and I dont know the height of the cab of the land launcher to do the maths. Therefore it is highly likely that any CAMM in a forward sile at deck height ...

Moved from T45 thread.... How can you ensure the safety of the Amphibious Task Group if your T45's are 200nm away with the CSG? I doubt the escorts would be 200 miles away.
