Re: Type 31 General Purpose Frigate [News Only]
A planar array simply means a flat two-dimensional array of antennas. In our context it implies that each element is the same , i.e. that each element has a phase shifter, as opposed to (say) a linear array where each row of elements are controlled by a single phase shifter. I don't think that you c...

Re: Type 31 General Purpose Frigate [News Only]
I would have thought that the real distiction is that, in the AESA system, "each element of the radar antenna now has its own transmitter, receiver and phase shifter", rather than each element manipulating a common signal feed (PESA). That said, an FPGA sits on the boundary between ASIC an...

Assuming all of them is NOT related to RN vessels crewing, I cannot believe You make my point for me :) The truth is, of course, somewhere in the middle, but, as the focus is on getting crews to sea, then we can perhaps, believe the RN when they say that the situation is nearly resolved.

Re: River Class (OPV) (RN)
Simple calculation shows us that RN is lack of trained manpower for 1600 souls. If about a half of that shall be assigned to ships, it means 800 crew is lacking = 4 T23 or T45 do not have a crew compared to the RN requirement. Donald-san, the RN is short of 1600 personnel is all that we can accurat...

Re: Type 31 General Purpose Frigate [News Only]
Have you got a decent source that confirms it is? I've posted this link before, back in the mists of time - as a whole it's a pretty decent history of radar development by Decca, so interesting in it's own right. You need to read forward from "The Active Array Revolution" to get to the st...

Why would you spend 175m on a patrol frigate? Sorry - should have been clearer.

That sort of criticism can be very damaging to a QCs career (as in, don't think you'll be moving up to the judiciary any time soon - the choice of words shows poor judgement).

Re: River Class (OPV) (RN)
What is the OSD now for the RB1's? Can we really expect them to go much beyond 2025? Probably 2028 would be the latest- that would be 25 years service for the first of the class. All 3 B1's will have had a major refit by the end of this year, so they are in good shape for now. Agree with the rest o...

Re: River Class (OPV) (RN)
Trust me, it needs a 3D system. If it didn't and 2D was good enough, the target could be at a given bearing and range but might be at 10m above the waves or 10,000m. CAMM's little RF seeker is not going to find or hit anything with that level of uncertainty in the intercept position. T26 - Artisan ...

Re: River Class (OPV) (RN)
as a 2D radar it can only track bearing and range. ... and velocity, don't forget. It's true that 2D radars don't determine altitude, without a secondary 2D operating in the vertical plane (most air traffic control radars are 2D with a height-finding secondary - it's much cheaper apparently). I don...

Re: River Class (OPV) (RN)
A couple of points of information: the B2s do have an Ops room. It's described as small and I've no idea how many terminals it can fit, but it exists; the Scanter 4100 can track up to 100 air targets (up to supersonic aircraft) and a total of 500 targets in all out to 90 miles and 30,000ft - it can ...

personally not convinced on the short term need for the 40mm As I say, only if confirmed as secondary armament for the T31, I wouldn't want to see it introduced specifically for the RB2s.

Re: River Class (OPV) (RN)
Agreed that the level of up-arming will be determined by the tasks that the B2s are asked to undertake. Currently we have retained the B1s for UK EEZ patrol. They, clearly, do not need up-arming in any way to carry out that role. Of the B2s, from recent announcements/ speeches etc, it looks as if on...

Re: River Class (OPV) (RN)
If the RN follows through with its declared intent to deploy the RB2s worldwide, then it is likely that they will, at the very least, be transiting through some fairly risky area. In order to do that without themselves requiring an escort, a simple change to a main gun that is effective out to the v...

It sits somewhere between rim-116 and ESSM so it’s classification isn’t exactly clear.

In software terms it sits closer to PAAMS tha...
