The Ministry of Defence has confirmed that three of the Royal Navy’s Type 45 destroyers are currently operational, following a parliamentary question on the availability of the class.
Responding to a question from Lord West of Spithead, the former First Sea Lord, Defence Minister Lord Coaker stated that HMS Dauntless, HMS Dragon and HMS Duncan are operational.
In his written answer, Lord Coaker added that upgrades under the Type 45 Power Improvement Project remain on schedule and that overall class availability is being managed to ensure the Royal Navy can meet its operational commitments.
“The Type 45 Power Improvement Project upgrades remain on target and Class availability is maximised to ensure that the Royal Navy has been able to fulfil all of its operational commitments,” he said.
The response follows earlier parliamentary answers issued in December, which confirmed that three destroyers had completed the long-running Power Improvement Project. At that time, ministers stated that HMS Dauntless, HMS Daring and HMS Dragon had finished their PIP upgrades.
HMS Defender and HMS Diamond remain in refit undergoing conversion, while HMS Duncan continues in service and is due to enter the upgrade programme during her next docking period at HMNB Portsmouth. The Power Improvement Project, delivered under Project Napier, is intended to resolve longstanding propulsion and power-generation issues that have affected the class since entering service. These problems have historically limited availability, particularly during operations in warm climates or under high electrical load.
Under the upgrade, the destroyers have their original diesel generators replaced with three larger and more reliable units, alongside changes to the high-voltage distribution system. The Ministry of Defence has said this provides improved redundancy and a more resilient electrical architecture to support the ships’ radar and combat systems. The work requires major structural modification, including hull cuts and extensive internal reconfiguration, making it one of the most intrusive refits ever undertaken on an active Royal Navy surface combatant.
Despite the scale of the engineering effort and ongoing global tasking, the Ministry of Defence has maintained that the programme remains on track, with all six Type 45 destroyers expected to complete the upgrade by 2028.












Any update on when any of the T45s will get their NSMs and their CAMM farms? Are they also getting Ancilia?
It has started. Defender has had CAMM silos fitted and will rejoin the fleet in the summer. Not sure about NSM.
She had been photographed with the new blocks installed forward of the Sylver complex just a few days ago. Only side on shots have been taken so far but it looks like a huge step up for her, NSM infrastructure is not present on any destroyer yet. Either way, this news means the RN now has the most VLS laden surface vessel in Western Europe with a total of 72 cells – granted GWS-35 isn’t on par with MK-41 or Sylver but still we can have some playful optimism for once.
Well its an improvement, 3 fully working, No navy in the world has 100% of its ships working any way, Just fix the subs now they are in a sorry state.
A great photo today on Navy Lookout ‘X’ with 4 Type 45s tied up in Portsmouth; HMS Duncan, HMS Dauntless, HMS Defender & HMS Dragon. While HMS Diamond is in refit [per article] & HMS Daring has completed PIP upgrade, perhaps Lord Coaker might like to explain what he exactly means by ‘HMS Dauntless, HMS Dragon and HMS Duncan are operational’ as all three are currently in port.
Perhaps they are getting an MOT, anyone seen any tyres being kicked?
Isn’t being ‘on the wall’ now the new definition of operationally deployed?
Isn’t this actually because of the nut zero push from Millibrain?
If they go to sea they create CO2 so……
I’m afraid I’ve stopped taking any of this garbage seriously as the people uttering the garbage are not serious.
By your logic, the only Typhoons that are ‘operational’ are those in the air 🤦🏻♂️
It’s possible to be operational, and still dockside, ready to be deployed on operations.
Do they have to be at sea burning fuel and annoying the crew just for the sake of it?
Operational? At sea? manned? fully equipped?
Yes Geoff a bit nebulous as usual isn’t it, expect nothing different these days.
So I wonder when as it has completed its refit/conversion HMS Daring becomes operational, I assume it will (at least hopefully) do so when Duncan enters the refit programme. Do we know when her ‘next docking period’ is?
This is propaganda. Believe anything HMG gaslighters spout? You deserve a straightjacket and meds.
😂
Just demostrates how few ships we have. A ship that isn’t operational doesn’t count – only ships that are available now count. We simply need a lot more.
Does this mean another 40 or 50 years of service time?
Away from ships i have always wanted to know how many C2 tanks are operational, not on paper but in the real world now today, i bet its less than 40%. MOD loves telling us all how much kit they have but what precent of it works? how much could be depolyed in 72 hours?? I think the real numbers would be very low, .far too low to publish.
In addition to the derision from most posters, note the spin and repeated emphasis on “meeting all the RNs operational commitments” which, by design, ignores the fact that those commitments have shrivelled up like a old date due over the years due to lack of assets.
What are those commitments, HMG?
Armilla patrol?
APT N and S?
Standing Nato forces in the Med and Atlantic?
The FRE and TAPS?
How many are gapped or plain quietly dropped and the public do not notice?
You could have a solitary “commitment” to have a ship sail out into the channel and you’d be grandstanding that the RN is managing.
Meanwhile, our solitary SSN has gone off to Australia, courtesy of yet more grandstanding.
You’re a joke, HMG, as bad as the bunch before you, possibly worse.
