Now what I would like to see is our B2 Rivers fitted with two of these on the wing points plus a 57 or 40mm main gun

Many thanks yes 2 of these fitted on the wing points would give the B2's 16 ready rounds plus they could carry 16 more giving them 32 Missiles plus a 57mm or 40mm and a Camcopter this would not effect there day to day but would increase there defence 100 fold on there global duties. we could also add 10 Hero 120 loiter weapons that could give them a 60+ km OTH strike option again these can be kept in the ships mag and launched from the flight deck as needed not effecting the ships day to day

Love to see a T31 or T26 in that color scheme complete with appropriate red emblem (is that the right word?).

For example, HMS Glasgow could have a broken beer bottle :D

And, "a platoon of RM" is not always onboard. You can see in many twitter images. HMS Forth does (army), HMS Medway carries several for HDHR in summer, HMS Trent "sometimes" carries marines, and HMS Tamar and Spey, I've never seen them? No always.

But, if you include the 50-more soldiers as her crew, yes, adding two 8xLMM turret is doable, no objection. Note that, the moment they disembark, the OPV will lose its capability to operate LMMs. For me, carrying 3x LMM turret operated by them will be a good "add-on" in a bit higher threat region. After landing, the 3x LMM turret can be also landed with the soldiers for their air-defense. Not bad.

Yes, I knew it. And I think it is to "enable" smaller crew. That's it.
the 40mm and LMM mounts can be operated by 1 man each = 3 from the ops room and the Crew is 45 for a B2
the current 30mm and small arms take 6 all stood outside in harms way

Some of the newer guns don't even have the chair at all, but that doesn't mean the older cannon needs to be manned at all times.
Yes the 30mm can be controlled but the small arms points still need manning so six crew needed to defend the ship
Let's make it clear....

1: I understand you are proposing to replace the 30 mm with 40mm (item-A).

But, are you also proposing to replace "2x 7.62mm miniGun and 4-6x 7.62mm" with "2x 8xLMM turret" (item-B) ? Or are you proposing adding "2x 8xLMM turret" to to small guns?

I was commenting assuming the latter, and hence needs good number of sailors are needed to be added. (say, item-A will add 2-3 more crew, and item-B will add 3-4 more).

2: In addition, I think if such heavily armed and to be used in "more" harm way, the damage control of River B2 shall be improved, and 10~20% more sailors will be needed, independent from item-1.

As a result, 5-7 more sailors will be needed for item-1. In addition, item-2 may require 4-8 more. (item-1 and 2 is independent discussion)

3: And here I assume whatever the number of the River B2 crew now (35 or 45), they are all already busy and cannot handle "additional" tasks. I know they clearly stated that all crew are multi-tasked (if my memory works, in some movie of River B2, the crew are saying so because the crew-size is small). And I guess the total number of crew onboard is what is really needed, no redundancy.

For example, I understand, when the EO/FCS maintainer is "free" because he/she has no such work for another week, I'm sure he/she is not enjoying the life as a passenger but busy doing other tasks elsewhere.

Lets be very very clear all RN ships including the B2's have crew redundancy due to injury and sickness and all crews multi-task it the nature of life at sea

Again to be very very clear my armament would be 1 x 40mm , 2 x 8 round LMM , 3 x 12.7mm and I have NOintention of knowingly sending them in to harms way however in this new world were 1st gen anit ship missiles and drones like the Shahed 136 are becoming more and more seen in grey zones for me due to there overseas roles they need this new level of defence

So you are proposing to replace 2x 7.62 mm miniGun with 2x 8xLMM turrets. Interesting (for me 7.62 mm miniGun is the main weapon on OPVs).
[EDIT] In this case, it is just a comparison of man-power needed for 7.62mm miniGuns vs 8xLMM turrets. This is not clear (gatling gun is not a simple mechanics).
..I have NOintention of knowingly sending them in to harms way however in this new world were 1st gen anit ship missiles and drones like the Shahed 136 are becoming more and more seen in grey zones for me due to there overseas roles they need this new level of defence
Understood. So here we had difference. I was thinking that such an up-armed River B2 shall be treated to be facing more threat, and thus shall be upgraded in damage control than they currently are. We just differ here.

On the other hand, it look like you think LMMs is better in handling gray-zone tasks than 7.62mm miniGuns. I have a different opinion. 7.62mm miniGuns will be better in many cases. It can do good warning shots, while not so much for LMM. Of course, the main gun (30/40 mm) can also do it, but 7.62 mm gun is the main weapon in "much more closer" encounter = when it is difficult to identify a stupid-but-peaceful-fishermen against professional-terrorists.

But I do agree there will be some theater (like Red Sea) LMMs/StarStreak would be useful and thus I think adding 3xLMM portable turret be better option (not replacing the miniGuns). Of course, this needs more crew.
Lets be very very clear all RN ships including the B2's have crew redundancy due to injury and sickness and all crews multi-task it the nature of life at sea
Thanks. I know. And I think that (it is very very clear that) "crew redundancy" is always needed. If you add two 8xLMM turrets, you add tasks but you need to keep the redundancy. And thus you need to add your crew. I think this is a very simple argument.

For example, (I "guess" you will agree) additional crew cannot be avoided when you add 6-8x 8xLMM turrets to a T31 GP frigate. And this is just a x3.3 scaled number for your River B2 8xLMM turret proposal. Also note that an OPV shall have even LESS redundancy ratio than a GP frigate.

HMS Trent's low activeness looks like because of some malfunction. Hope she over come it soon.

I guess yes. It looks like smaller than CB90, which is ~25t. River B2 crane can handle 16tonnes.

Looks like no UK military vessels are around Caribbean? HMS Scott?

HMS Forth has been at Falkland island from Jan 2020. It is "just" 3 years. No surprising to have a maintenance/inspection period, but, yes I agree interesting to see it is not taken on site. RN did not continue the "on site maintenance" contract, or simply downgraded it limiting to "not heavy maintenance" to save money?

At these days, there were only HMS Clyde. In deep maintenance, HMS Echo/Enterprise was sent in place. As there are 5 River B2s now, "rotation" might be logical it could be. Any info?

HMS Spey. Continuing her job tirelessly. Very high activity = longer sea going days.

Clear example of "being simple has its own strong merit", because it can be used more intensely. Of course, escorts need to be complex to fight. So, combining these two types of assets is a very good approach.

How many days do they spend at sea and in port. It seems to me they spending a lot of time in different ports something like 10 to 15 days at sea followed by a 4 to 5 day port visit each time

The RN is getting one. How useful it will be will depend on the role it’s intended for, I’d say for the Gulf it’s ok and better than ScanEagle. I’d also say that it would be a good addition to the B2 Rivers in their current patrol role in regions where other UK air assets are limited.

IMO this actually quite embarrassing for the UK.

Why are all of the RB2s not getting this system?

Why not have 8 to 10 units to spread across the escorts, amphibious and OPV’s.

What if this single UAS gets damaged or lost?

It a sad state of affairs that this is the best that RN can do.

To be clear one system comes with 2 air vehicles a control station and logistics package

As said before 100 million could buy 30 full systems i.e 60 UAS's
