Thank you to all of you who have Followed, Listed, Liked, Retweeted and Replied over the years. You teach me at least six new Things every day! In gratitude, here's a mini-Thread of a few Threads that I have posted up over these years for your nostalgic pleasure. Grab a cuppa.
A thread looking at the Royal Navy's cancelled plans for a 155mm deck gun:

A thread with an opinion on Type 31 armament:

A thread looking at the Royal Marines initial 3-year plan for transformation:

A thread on what the Army's future looks like inside my head:

A thread on how similarly equipped Argentina was compared to the UK in 1982:

A thread on the new drone quietly being employed by the Royal Marines:

A thread with pictures of the various Mission Modules available to load on the back of the Boxer 8x8 Drive Module:

Note: There are three versions of Drive Module, the UK has ordered the A3 with the more powerful engine output and up to 38.5t GVW.

A not-a-thread but an interesting video anyway on the development of the highly-secret VT Proximity Fuse shared with CANUK-US right at the beginning of Five-Eyes and the Special relationship:

A red-team style thread on shaking up the British armed forces in 2017:

A thread on clearing away cover:

A thread on Precision Engineering:

A thread on a modern Universal Carrier:

A thread on Batteries and how the UK was pulling together component industries into a whole:

A thread of sketchy drawings showing how a family of vehicles can be based on one platform:

And finally, a thread beginning with a video interview on the V-280 Valor features by Vago Muradian. This is *very* interesting due to the comment on the US Army realising they had relevancy issues where the USMC could influence a Theatre.

Presence.

⚙ CAVALRY, TURRETS & CANNONS

The KNDS team very kindly provided an in-depth tour inside the RCT30 equipped Mission Module pictured below. Within was held an invaluable, and frank, discussion about both the equipment and the roadmap moving forward.

The Mission Module is currently configured for the Bundeswehr requirement. As such there is much similarity with their latest Puma S1 including turret equipment itself and the "office" where the commander and gunner sit. The uncrewed turret approach provides more room inside the cell for dismounts and equipment.

To move from Puma S1 standard to RCT30, with features such as dual land and C-SAT target engagement, the turret's modularity was intentionally matured and here's where the conversation deepened.

1/Image
Sensors

The optical and optronic sensors, together with the MUSS tower, can easily be replaced with alternatives.

At the moment, Challenger 3 and Ajax both share Thales Catherine and Orion sights. These are GVA enabled for the British AFV's and the RCT30 turret can accommodate.

3/Image
Cannons

KNDS themselves are in deep discussion as to which cannon would best suit the British Army in a Cavalry or an IFV configuration, whether Mechanised or Armoured.

Three cannons dominate the conversation:

The Rheinmetall MK30-2/ABM is the most seen on Puma and RCT30 (PuBo). It has a growing user base with German Puma's and Boxers being joined by Australian and now Netherland Boxers. It is considered proven the most accurate of the three. Compatible ammunition is made solely by Rheinmetall for now, but UK selection would also see cannon, barrel and ammunition production licenses.

It is not widely known but the Mk44 Bushmaster II has been confirmed as already integrated with the RCT30. Bushmasters advantage is it can fire a range of 30x173mm including the MK30-2/ABM natures.

Finally CT40 is also a possibility though would take longer, the RCT40 not being as mature as the RCT30. Ammunition (below) is produced in the UK and France.

The penny-wise pound-foolish Apache/JAGM saga continues.

The UK is now buying 3,000 JAGM missiles for $957.4M.

That equates to $319,000 per missile for a system already integrated onto our AH-64E's, that the UK has already trained on, which the UK has already paid for and received examples of for handling, from an Ally who is supposedly covering all extra costs of development, leaving little to no NRE expectations for the UK to bear.

Even if we go with the highest Brimstone 3 cost of £175,000 per missile which is meant to include Brimstone 3 R&D amortisation, even if we go with double the integration cost the UK was meant to "save" at £150M, the UK would have saved £110M by sticking with our own developed and proven system.

This does not even go into details such as re-investment in industry via procurement, tax recovery to Treasury or potential for exports (Poland's own AH-64E purchase is a vast missed opportunity). The UK already knows how to use and handle Brimstone eliminating most of the NRE with the system, and we have heard from defence ministers on the record in Parliament of the superior and battleproven hit rate of the Brimstone in active Operations compared to Hellfire based systems such as JAGM repeatedly over the years.

If we do take the lower of the purchase price per missile that is known for Brimstone and the £70M quoted as being "saved" by not integrating Brimstone on Apache, then for integration and purchase of 3,000 Brimstone on British AH-64E's we would expect to see a lower end cost, using DE&S own figures, of around £385M, saving almost £400M on this purchase compared to JAGM.

Even the £110M saving at the higher prices is desirable right now and would lead to further savings in future.

It is quite clear that the promised JAGM price reduction has not occurred.

BS was called at the time of the claims and these calls have clearly, demonstrably, been borne out.

This huge expense on an unproven foreign supplied missile with variations in reliability of supply, when a higher performing and perception-busting lower cost British missile exists and is in production, does not meet the claims at the time that JAGM would save the taxpayer money and should be both questioned and investigated.

Article on the purchase here:

Meanwhile the Army is at great pains to show us WOLFRAM and the Mounted Close Combat Overwatch (MCCO) money being spent on Brimstone 3 integration onto their ground vehicles. With so much effort in Brimstone on Ajax, Boxer and Coyote, it is reasonable to expect the AAC to follow.

Image

Image
With the first of the planned 16 Protectors arriving, the RAF already has faith in the Brimstone missile and has not signalled that they do not intend to use it.

As an aside, Protector aircraft cost "just" £15M a piece based on the last contract, again with NRE mostly paid for now. By saving money integrating Brimstone on AH-64E instead of JAGM, the RAF could have the funds to double the number of Protector aircraft and integrate more equipment onto them while still having cash to spare.

⚙️ An approach to improving both Fleet Husbandry and Industrial Capability Husbandry for Army.

⏺️ Low Rate Production
⏺️ RESET Programme

1/ Image
⚙️ It is no secret that the Army's fleets have not received adequate TLC. Vehicles left outside in the British climate, insufficient spares ordered, vehicles cannibalised routinely.

2/ Image
⚙️ Similarly, it is no great secret that the very industrial base that the Army relies on has withered due to lack of engagement and orders. Infrastructure, sites, facilities, plant and skills have been allowed to erode.

⚙️ How the US Army's RESET program interacts with the M2A3 Upgrade and M2A4 Acquisition Programmes.

Oversimplified for illustration:

RESET rebuilds an M2 to pre-combat condition.

M2A3 upgrade takes rebuilt subsystems/parts and assembles/integrates them with new subsystems.

1/ Image
Red River Army Depot handles most of the RESET program for Bradley.

RESET restores to pre-combat condition, the work does not extend to zero-mile.

A Bradley is stripped into parts bins. Parts are refurbished and only replaced if defective or overly worn.

2/ Image
These parts are then passed to BAES in Pennsylvania where they go through Final Assembly, Integration and Testing before being returned to inventory in a pre-combat condition.
