HMS Dragon is eyeing a return to the fleet in 2024 as work to install new engines reaches a notable milestone, say the Royal Navy here.

The Type 45 destroyer has been undergoing major upgrades in Portsmouth since March 2022 and, nearly two years on, one of Dragon’s new engines has been started for the first time as part of critical trials. 

The ship is the latest of her class – after HMS Dauntless and HMS Daring – to go through the Power Improvement Project (PIP), which addresses the resilience of the engines and power generation driving the many hi-tech sensors, systems and weapons on board.

“To make the necessary upgrades, the two original diesel engines were removed and replaced with three more reliable, more powerful, cleaner generators.
Ultimately, the ship will be more powerful – 4,000hp to be precise – reliable, greener and ready to embark future weapons. Before returning to sea, Dragon is undergoing trials afloat in a non-tidal basin in Portsmouth which test each of three engine installations is correct, integrated effectively into the workings of the ship, can be controlled remotely and, eventually, that they can all work together to power and propel the ship.”

HMS Dragon heading back to the fleet

Dragon’s Senior Naval Officer, Lieutenant Commander Fiona Stephenson, was quoted as saying:

“The inaugural roar of Dragon’s new engines marked the beginning of the next chapter in our return to the fleet. I am proud of the hard work of our marine engineering team and industry partners and look forward to delivering as one team as we breathe fire into Dragon.”

Marine Engineering Officer Lieutenant Commander James Baddeley added:

“It is really exciting to see the PIP installation coming to life to increase the capability of the platform, the successful first start is testament to all the hard work which has gone into the design and installation onboard.”

HMS Dragon is the first of the Type 45s to undergo PIP in Portsmouth, with HMS Dauntless and HMS Daring’s work taking place at Cammell Laird.

“HMS Dauntless returned to the Fleet at the beginning of last year, deploying to the Caribbean to support British Overseas Territories during hurricane season and counter drugs trafficking in the region. Her successful actions on that deployment underscored the success of the major engine upgrades. PIP is being delivered under a major design and manufacture contract between the Ministry of Defence and BAE Systems, and delivered in collaboration with BMT Defence services and Cammell Laird.”

Are these to get NSM as well or are the 11 sets for the T23s and the up and coming T31s? NSM seems a reasonable choice, with a quick turnover for the right price.

Yup

One of the T45’s is having NSM fitted as we speak.

Quick upgrade – in relative terms.

First of class firing trials will be involved as always.

Would NSM mod be completed for Daring and Dragon, before returning to the fleet later this year? Additionally, wonder whether Defender PIP & CAMM mods could be expedited? Once Daring and Dragon return to fleet, Duncan and Diamond inducted into same refit program, one at Portsmouth, the other at CL? 🤔

Uncle Sugar could have a serious near-term and continuing requirement for the T-45s in the ME theater, and potentially, SCS. 🤔

NSM -bolting racks on and fitting cabling / fire suppression is no big deal.

In fact I can’t really see the physical fitting as any kind of deal.

The issue is clearances and first of class trials.

Has Somerset test fired yet? That will be the CMS test with an inert warhead for the first shot. So I suspect that has happened.

I suspect in the current exercise she will do a live shot.

With CAMM It depends what is fastest to do Mk41 or independent tubes.

I think RN is moving towards, for sensible reasons, a mix of tubes. Some quad packed for numbers and a few independent.

The reason for the Independant tubes is recycle rate and not needing a totally clear deck in a save-the-ship-emergency. Reloading is easier. They can be fired at the same instant as ASTER or NSM. So there isn’t a defenceless window when a heavy missile is being fired caused by efflux etc. which is a bit of a single silo approach problem.

11 sets of NSM seem to be more than enough when considering we only have 7 available Frigates and 2-3 available destroyers at the moment. (Recently published that of 11 Frigates 4 are inactive with two planned to be scrapped due to lack of crew.)

Reading an article on another site about Navy land attack capabilities now and in the future (as this missile has some land attack capability), it seemed to suggest only some will get them by stating something like ‘..hasn’t been revealed which of the T-45s will get them’. Like to think all will get them esp as T-23s are dropping like flies, but we will see.

I think the RN should opt for another 4 or 5 or so NSM sets and fit out all the escort ships available- so 15 if my calculations are correct. They can be transferred over across to type 26 and type 31s when those vessels finally enter service. The type 45s haven’t had a very strenuous service career to date so should be in a good material state to see them through to their out of service date. If money could be found I’d like the Bofors 40mm guns fitted and the sea ceptor fit accelerated to ensure an air… Read more »

Well the fuel tanks are the same size so if the engines uses less juice then the ship goes further between refuels?

That increases operational range.

Is that better?

The 3 new Diesel-Generators will be more efficient and powerful than the old ones. I would not expect the range to be reduced dramatically. The 2 gas turbines generator (GTG) are the gas-guzzlers but these are for max power and when going at speed. Most of the time using one GTG and one or two diesel generators would be sufficient. Using all of them is for when the ambient sea and air temperatures are very warm and all the Air conditioning is running – like when operating in the Gulf or Red Sea.

I was implying the range would increase.

Currently a T45 has to use a GT plus DG’s when underway.

With the new setup it can cruise at low speeds on DG’s alone so I would expect big fuel savings.

No it doesn’t You could split the switch board and have a GTA set running FWD with the other GTA running AFT. You can have one GTA running the whole ship with the DG set as emergency back up. The old DG sets were used during RAS and entering harbour etc as emergency back up to the GTA. With the GTA issues the old DG sets where being run all the time , something they were not designed to do. The New DG sets can power the ship without the GTA for as you said slow speed but the DG… Read more »

In all cases the word ‘GREEN’ means reduced CO2 emissions, does anyone think that this improves performance?

Supportive Bloke

Reply to  Colin Brooks

If you use less litres of marine diesel per kWh generated then that is simply more efficient which is greener as a byproduct.

As these DGs are massively more powerful I can’t possibly see how that would degrade performance.

So I’m lost as to what this comment is really about.

I’m personally rather more bothered about particulates and NOx than CO2 and these DGs will produce much less particulates and NOx than the old ones.

The are quieter, more power and more fuel efficient what more do you want.

Exhaust gases should be cooler to given improvements in efficiency and design. It is impossible to say that without knowing how these DGs are set up – which we never will.

That is just not true only modifying old designs not really suitable for such upgrades might suffer somewhat. All RR new engines for example will be far greener, but also far more efficient, powerful and superior to their predecessors. Indeed all modern car engines are greener, more efficient and generally more powerful than predecessors, the only potential downside might be complexity but that’s not a given indeed RR aero engines are generally less complex in some ways having less moving parts and compression stages as a rule.

Hi folks hope all is well.
This is all very well and encouraging to see these great ships being upgraded and made fit for purpose.
However, I’m slightly concerned about the time it takes to carry out work, not just the Type 45’s, although all work appears to take ages!
I suppose my main concern is in the event of an emergency, would it take as long? Hopefully not. Would we have enough skilled staff to work 24/7 in such a short time frame?

It is amazing what you can do when there is some real pressure!

The reality is the one closest to returning to service would get a full team to get her out.

There is always a rapid return to service program for all warships being worked on.

Obvs if it is in dry dock with holes in the hull and engines out that won’t be fast.

The Type 45’s had been designed to take MK41 VLS,but due to cost cutting they were put into the FFBNW category,if that has changed we would have heard about it by now.

You may have confused the announcement that T31 & T26 will have Mk41 VLS fitted, which in the case of the T31 especially is a great boost to its effectiveness & versatility. I thought the ame until others pointed out that the space designed for the eventuality had been taken by a gym & the new Sea Ceptor farm. The latter substantially increases the SAM missiles carried, improving survivability v stauration attacks.

With what’s going on in the world right now, not to mention what else may ‘kick off’ we really need all 6 T45s ready for operations. Here’s a question for the ones who know about such matters, I believe HMS Richmond has replaced HMS Diamond on operations, is Richmond as capable as a Type45 in targeting & engaging airborne threats? As far as I’m aware Type 23s have no Phalanx/ ciws, is this a bit risky?

True, capability is significantly lower not being a specialised air defence ship and also has no ciws, it has been commented on another thread. The fact the US recently had to use ciws highlights the concern. Frankly its a disgrace that any warship lacks ciws, the cost is miniscule in comparison to the value of the ship and its crew.

No, it doesn’t have the range the Aster missile carried by the T45 can reach. Nor the dedicated longe range radar. No CIWS is a gap, though the sea Ceptor missiles carried hopefully would take out misiles or drone before they get within its minimun engagement range. Diamond should restore its missiles etc, rest its crew in Gib & hopefully be back on station in a week or so. I’m sure Richmond will do its best & USN/other allies will compensate for her limitations, but this is where only building 6 T45 to replace 14 odd T42s comes back to… Read more »

The LRR doesnt control ASTER engagements …thats a Sampson job on T45.

A T23 with Artisan you can identify and track targets at over 100miles. You control the missiles with separate data link domes fwd and aft. You need artisan to tell you where the missile and target are so the system can calculate future intercept point and send the info via the data link. The Ceptor system also has other modes available to it for engagements.

Because the new CAMM missile equipment and materials for the T45’s are longer lead items, they need to be ordered a few years in advance. Which means the new equipment for Hms Defender has just been produced, and will arrived at the yard in due course, or some of it already there, or arrive later in year.
No new missile equipment was produced for Darling or Dragon yet. You cannot produce complex equipment at a drop of a hat!

It’s not like this is new. It was announced to the public over a years ago and that means negotiations probably started a year or two before then. Could easily have all the parts made by now if there was the desire since they are already designed just needs to me modified a bit to fit. The missiles themselves are in stock.

In Ukraine’s case, in wartime mode, the wheels of procurement turn very fast with the funding for it as well.

That is not the case with the MoD in Whitehall. The wheels of bureaucracy turn more slowly in Peace time. The need to arrange funding etc, and negotiations with supplier, and to drew up contracts, requirements, can take weeks alone, sometimes months.

Yeah for sure and also takes longer as needs to be tested to be fully safe etc, but 2 years they couldn’t achieve that? Instead will have to pay more as it involves dry docking twice instead of once and hits capability for longer.

Alway good, having just 6 Air defence destroyers, for one to be getting closer to returning to ops after refit. The world is far too dangerous to be juggling tasking from just 6 hulls. We need more destroyers that can “sweep the skies” of drones & misiles. Saturation attacks seem the choice of our enemies, so we need these long range assets as well as shorter ranged frigates with Sea Ceptor.
