It’s a true phase but does that mean more money on military equipment?

This country isn’t going to be invaded by a foreign army nuclear weapons have seen to that. I would argue the same for nato territory. There will be provocative actions along its borders that will require conventional force to observe and deter.
Agreed, so what does that look like if cost is not the driving factor?
Your then into harassment and disruption of flow of material, people, information that destabilises norms. This has been labelled many things over the years the latest is the grey zone. Some may refer to it as economic war.
Closing or massively disrupting Suez has widespread and extremely costly knock on effects for the U.K. population.

If it’s only France, U.K. and U.S. to protect the rules based order for the long haul then so be it. Permanent seats on the UN Security Council has costs attached to such a responsibility.

Deterrents provide the best value for money, especially if they are never used.
Do we increase the safety of our citizens by becoming more resilient as a nation re-shoring manufacture to improve our industrial base, increase resilience in energy, food, water and chemicals do we then export more to our allies to help them do the same things and govern along the democratic principles we champion.
Absolutely but it’s only one part of the matrix.
Do we need to be robust on knowing who comes here and what cause they champion and who maybe sleepers for hostile regimes? If we spend money on that is that defence?
Yes but it’s primarily in the border force/domestic security sphere.
In terms of numbers you would need to know the working that went into the number. Was it we think we need 12 so we will ask for 18 because we know some will get cut. Did I know I needed 4 to get 1 to sea because the tech was quite unreliable in the past? Or was that just what was there already. In the end it’s people, spares and the industrial infrastructure not equipment that is in short supply you see it across the board the classic example is in the submarine fleet right now with dry docks.

If the equipment lines are running and you build capacity into them even if you’re not using it all you can get equipment reasonable quickly. But that’s more about having sensible industrial strategies than equipment.
No argument but a purely risk based SDSR would be fascinating document.

Much of SDSR 1998 still rings true but even then it’s clear that ambition was receding and pressure was being applied to divert spending.

Within the current funding envelope the UK Armed Forces are completely hamstrung and at the mercy of events. IMO the lack of mass and starvation of resource will prove to be unsustainable, even in the short to medium term especially if a second major conflict erupts before the current one has concluded.

For this reason and even with the ongoing headcount crisis, RN must prioritise maximum hulls in the water. Clean sheet T32 and T83 designs are luxuries that RN cannot afford to be seduced by at present.

It would be prudent for HMG to formalise a plan for a rapid 30% increase in defence spending, if the unthinkable was to occur, and have a clear idea of how to reorganise UKPLC to swiftly react to such a procurement shock. The money would be the easy part, it’s the industrial capacity that is lacking now.

Ramping up production even if just to support allies almost seems implausibly expensive now. Perhaps it’s time to step back from some of the hyper expensive bleeding edge tech and invest a higher proportion into mass and presence in an effort to successfully deter.
Cost is always a constraint that’s reality no one can do it all. It’s why you have to choose priorities and do them well. I think we miss the fact we spend more on defence than any other equivalent sized country we have a very big budget we waste a lot with short term decision making.

Suez has been closed in the past and work arounds do exist but nothing lives in a vacuum. Presence is important for deterrence I agree, in these areas but presence requires resilience and if that’s your choice then you need to resource it as such.


My point is keeping people safe is very much more than simply the MoD and buying equipment for the military it is but one part and not necessarily the biggest part of it and in the work of finite spending choices always need to be made.


I know a lot of people exalt 98 sdr. I think it was not only fundamentally flawed in that it got its costing all wrong but it was also based around an interventionist foreign policy which is and turned out to be strategically illiterate.


They are neither hamstrung by finances nor at the mercy of events. They waste and act as if they are awash with money. There is no focus or willingness to take decisions to stick to a set of priorities. They want to do everything that applies to governmental and senior officers. Others with a fraction of the budget make better tradeoffs imo.


I would agree around the bleeding edge and to a large extent it’s around investing in the manufacturing of expendables and integration capabilities. One big thing that would help is taking a leaf out of the US on what they call LRIP for things and continuing to buy min quantiles even if there not needed per se by the military. That may mean binning some early equipment examples sooner specifically to keep the manufacturing going but strategically that maybe prudent. It’s significantly easier ramp up existing production lines than attempt to restart from scratch.

Our Japanese friends seem to be moving forward on their [definitely not] AAW cruisers.

https://www.navalnews.com/naval-news/20 ... or-fy2024/
The ministry pointed out that the size of the ASEV will be 1.7 times larger than the US Navy’s latest Flight III Arleigh Burke-class guided-missile destroyer.

Image
The ASEV will have a crew complement of about 240, which is much fewer than the Maya-class destroyer’s 300 crewmembers.

The Japanese Maritime Self-Defense Force (JMSDF) is expected to take delivery of the first ASEV during fiscal year 2027, with the second one in the following fiscal year.

The ministry expects the total construction cost for each vessel to reach about 395 billion yen as of late August.
Now the original concept was for even larger floating Aegis and missile batteries but that's been scaled back to something that resembles a more conventional warship. With a weapons fit similar to the current Maya Class, "including a Mk-45 (Mod.4) 5-inch/62-caliber (127mm) main gun, SM-3 Block IIA and SM-6 missiles."

I'm not suggesting we try to start developing Type 83 in this direction but it's certainly worth looking at what our allies, with rougher neighbourhoods, are doing.

Will wait with baited breath for someone else to propose an overgrown RC barge to become their main AAW surface combatant...

Those sm6 missiles are around 15m dollars each but I guess if your homeland is having ballistic missiles fired over it regularly you gonna prioritise air defence.

For us it will be most interesting were we go with radar and combat management systems. Aegis was on the table when type 45 started I’m sure it will be again.

As you say, they have a defensive requirement we should be very grateful we don't even vaguely come close to having.

If I had to guess, I'd say we're going to adopt AEGIS for lack of visible HMG investment, or joint enterprise, on anything that would be better. Heck we haven't even fitted the 45s with CEC.

Radar could be where we deviate, along the Aussie lines, with the AEGIS CMS but with an enhanced CEAFAR or something from BAE. My preference would be on the later for industrial reasons but, unless we start putting in serious cash to the sensor element of FADS before the end to the decade, our choices and benefits will get further narrowed.

Just a comment. SPY-7 is selected because it uses Fujitsu AESA node. Just a roumor, but may be true. Many thinks SPY-6 will be better considering the commonality with USN.

Thales Nederland going as far to say Collaborative Engagement Capabilities (CEC) is the future of Naval Warfare for them. CEC is a must have for networking input facilitating for the exchange and integration of radar data at plot level from other ships, shore and space sensors and systems, Thales CEC fitted in the MLU of the Dutch De Zeven Provinciën-class frigates along with the SMART-L MM/N replacing the SMART-L.

The Japanese Navy with their new A-SAM missile system developed a new data link, the Fire Control (FC) network to share radar information among its ships. Planned as complimentary to the USN Data Distribution System (DDS) data link for CEC, Japanese say the USN CEC aims to intercept approaching missiles and other missiles as far away as possible with the SM-2s and SM-6s whereas the Japanese FC network aims to efficiently intercept missiles that have leaked through the destroyers air defences with the A-SAM.

RN can achieve that within a decade, if prioritised, without the need for further funding.

It would involve replacing the T32 with five or ideally six Iver Huitfeldt AAW Frigates. Modestly upgraded with 16x Sylver cells added to the B position for a total of 48x cells. 57mm retained in the A position plus port/starboard 40mm’s and up to 16x NSM.

This would result in a potent vessel.

• 57mm
• 2x 40mm
• 16x Aster 30
• 40x CAMM in mushrooms or 128x quad packed
• 16x NSM

Clearly S1850M is possible but could Sampson be made to work in the A140 hull? A potential export goldmine awaits if so. If not maybe the 4D NS200 or Artisan would suffice.

It’s certainly not a gold plated solution but it’s cheap and fast and perhaps modest ASW improvements could be made to provide the AAW/ASW capability at a lower cost or if the A140 MNP multi role capability was prioritised, a stern ramp, 2x 15m davits and 2x Merlin capacity could be added whilst maintaining the amidships VLS silo.

The resulting fleet balance would be AAW heavy:

• 6x T45
• 8x T26
• 5x T31 GP
• 6x T31 AAW or T32 AAW/MR
• 5x RB2

A delay to the T83 until 2040 thereby allowing an extra 4x T26 to be built provides excellent fleet balance:

• 6x T45
• 12x T26
• 5x T31 GP
• 6x T31 AAW or T32 AAW/MR
(RB2’s decommissioned mid/late 2030’s)

This is undoubtedly the fastest way to grow RN in an affordable way. These are the type of solutions RN must find and embrace IMO.
So getting to where I would like to go would take more than a decade but there are things that could be done

First we have two great hulls to work from so no need to waste money designing a new one instead open a new 1.2 billion program for a new AAW Radar and integrated mast witch will fit on the Type 26 hull with a view to start fitting it from ship 7 and upgrading the first 6 at mid life refit then go on to build another 8 ships for 16 in total

As for type 31 build a second batch of 5 with Thales Sea Fire radar fit 16 A50 VLS in place of the forward 40mm for 16 Aster 30 and have 40 CAMM and 16 NSM amidships also add a Palfinger slipway under the flight deck for unmanned MCM/ASW and then sell the first 2 batch 1 ships

also upgrade the RB2's with NS50 , 40mm , 2 x 8 round Starstreak/LMM mounts and a Peregrine UAV

Just a comment. SPY-7 is selected because it uses Fujitsu AESA node. Just a roumor, but may be true. Many thinks SPY-6 will be better considering the commonality with USN.
Would note the Lockheed Martin SPY-7 is a AESA GaN dual-polarimetric radar that transmits and receives pulses in both horizontal and vertical orientation, as a result, the returning frequencies provide measurements of the horizontal and vertical dimensions for better discrimination of the size and shape of targets with a near 3D image.

The US Missile Defence Agency awarded LM the contract for the Long Range Discrimination Radar (LRDR) based in Alaska with its two very large 60 feet flat panel arrays which use the same dual-polarimetric tech for its ability to distinguish ICBM warheads from decoys in preference to a larger variant of the Raytheon SPY-6 radar. The Japanese after demos in the US by both LM and Raytheon radars also picked the SPY-7 in preference to SPY-6 for the ASEV.

So it would appear the SPY-7 is the more capable radar than the SPY-6 - if it lives up to its claims with its dual-polarimetric tech.

No thank you but I am happy to say we should not waste time and money on designing Type 83 and instead spend the money on designing a new AAW/ surface radar to go on Type 26

Depends how good T26 is as a platform. Considering how many problems the Australians are having, I say no. A new platform I believe is definitely not the costly part of FADS.

Agreed.

If the T32 has to happen then the AAW/ASW/GP/MR ratios need careful consideration.

If RN is serious about the T83 being a super-cruiser then only 3 or 4 can be expected and therefore other vessels are going to have to plug the gaps on singleton deployments.

How will RN afford to fill 96x or 128x cells on a T83? It seems completely illogical and such a large complex vessel is very likely to encounter delays and setbacks thereby throwing the drumbeat into disarray.

Not convined the T83 will be much bigger than the 45 as that would mean a drop in hull numbers, as the mai mission is to protect the CSG... unless the can get cheaper ships awell to make up the numbers, 4 x T83 cruisers & 2 more T31 with CAMM - MR ? guess only time will tell....

The RN has said they don't want supercruisers, that they want a distributed system. Why do you ignore it?
Instead of building a typical surface combatant with a mix of capabilities, the proposal is to build a ship of around 4,000 tonnes that is only equipped with high-end radar and plenty of VLS cells. (Main concept image above) The ship would have no guns (except light weapons for force protection), no ASW capability, no hangar and a crew of less than 50. Manning would be so taut that small teams might need to be embarked by helicopter or boat for specific evolutions such as replenishment at sea, preventative maintenance or additional force protection for high-threat transits.

The machinery and living spaces at the core of the ship could be armoured the rest of the hull would be hypoxic – ie. filled with inert gas and unmanned for the majority of the time. The ship would be very survivable but damage control would be using remote systems only with no re-entries envisaged, given the tiny crew. (This DC model is widely used in the commercial shipping world and some RFA vessels).

By simplifying the design to focus on a single role, the build and sustainment costs would be much-reduced and in theory, this could allow 3 or 4 times the number of hulls to be built for the equivalent price of a full-capability spectrum air-defence cruiser. More hulls increase availability and the force could be more widely distributed to provide a larger area of air dominance around the carrier strike group. The vessel would be reliant on ASW defence provided by other platforms in the group.
https://www.navylookout.com/options-for ... destroyer/
Procurement history has shown that trying to introduce state-of-the-art technologies en masse into a new complex warship may deliver an exquisite, expensive platform affordable only in small numbers. “What we’re going to do with FADS is not just introduce everything to be brand new at once,” he said: instead, the RN is seeking “to introduce something that will still be the best in the world but won’t end up being an ‘impossible-to-deliver’ portfolio of programmes that will make up FADS.” Here, Rear Adm Parkin continued, recent RN decisions to upgrade the Type 45’s Sampson and Long-Range radars and Sea Viper local area anti-air and missile defence capability, for example, are part of the process that will inform capability thinking and development for FADS.
https://www.navalnews.com/event-news/ds ... apability/
AT DSEI 2023, First Sea Lord Sir Ben Key described FADS as "...the replacement to our Type 45 Destroyer, but so much more than just about ships. A system of systems designed to be completely dominant.

Procurement history has shown that trying to introduce state-of-the-art technologies en masse into a new complex warship may deliver an exquisite, expensive platform affordable only in small numbers. “What we’re going to do with FADS is not just introduce everything to be brand new at once,” he said: instead, the RN is seeking “to introduce something that will still be the best in the world but won’t end up being an ‘impossible-to-deliver’ portfolio of programmes that will make up FADS.” Here, Rear Adm Parkin continued, recent RN decisions to upgrade the Type 45’s Sampson and Long-Range radars and Sea Viper local area anti-air and missile defence capability, for example, are part of the process that will inform capability thinking and development for FADS.

AT DSEI 2023, First Sea Lord Sir Ben Key described FADS as "...the replacement to our Type 45 Destroyer, but so much more than just about ships. A system of systems designed to be completely dominant.
This is just one of a number of options and with no fix way forward we can't know what T-83 could or would be at this time

I get inert gas for fires but how would flooding be dealt with in such a small crew in damage control situations giving that’s how the navy in peacetime have nearly lost several ships and how would they man the defence watches and air warfare battle staff with a crew of just 50?

Really do not understand why this isn’t a priority - it was part of argument by the Labour government why six T45s was ok.
Thales Nederland going as far to say Collaborative Engagement Capabilities (CEC) is the future of Naval Warfare for them. CEC is a must have for networking input facilitating for the exchange and integration of radar data at plot level from other ships, shore and space sensors and systems, Thales CEC fitted in the MLU of the Dutch De Zeven Provinciën-class frigates along with the SMART-L MM/N replacing the SMART-L.

The Japanese Navy with their new A-SAM missile system developed a new data link, the Fire Control (FC) network to share radar information among its ships. Planned as complimentary to the USN Data Distribution System (DDS) data link for CEC, Japanese say the USN CEC aims to intercept approaching missiles and other missiles as far away as possible with the SM-2s and SM-6s whereas the Japanese FC network aims to efficiently intercept missiles that have leaked through the destroyers air defences with the A-SAM.
Just to clarify The Dutch frigates aren't fitted with the American CEC system the article Nick is quoting from and Thales comments are about Collaborative Engagement Capabilities as the general process of exchanging target data and sharing weapons not the specific CEC system.

A networked system of sensor and effectors sharing data to come to the best effect, sounds a lot like the RNs FADS programme and similar programmes by French Navy and wider EU moves at similar collaborative systems\tech.

Likewise, I can see robots being used to handle hoses etc for fire fighting, but flooding? Having watched video of the training exercise that crew go through to stop flooding in a compartment, it's pretty complex to just detect where the flooding is coming from

Not difficult, seal off the compartment and loose it, then pump everything like crazy.

The automation is noting challenging. More challenging is making everything redundant to mitigate failures, and even more challenging is the cultural changes needed to make it happen.

One question is how would 4,000t T83 be able to take the top weight of a high end long range radar, the US Navy state that radar sensitivity scales as a cube of the size of the radar aperture e.g. the two new Japanese ASEV Aegis destroyers are said to be approx. 17,000t in part driven by need to mount a large variant of the SPY-7 radar with the necessary capabilities to track and target the ballistic and hypersonic Chinese and North Korean missiles.

Is RN thinking outside of the box and planning on fitting a new CW radar, with its two separate transmit and receive antennas, the main advantage of CW radars is that energy is not pulsed so are much simpler to manufacture and as they transmit continuously they maximise RF power on a target, standard pulsed radars spends the majority of its time listening for a return, have seen said the radar is "on" for a little over 7 seconds each hour and the remaining 59 minutes and 53 seconds are spent listening for any returned signals.

Pumping doesn’t fix the problem water is still coming in. Particularly if it was for example in the engine room.

Then loose that engine room, and switchover to the standby engine room. Redundancy is how to make it work.
