Name	Dragon
Ordered	December 2000
Builder	BVT Surface Fleet
Yard number	1064[3]
Laid down	19 December 2005
Launched	17 November 2008

Since March 2022, the Type 45 destroyer has been undergoing extensive upgrades in Portsmouth.

Royal Navy destroyer HMS Dragon is poised to return to the fleet in 2024, fuelled by the milestone achievement of installing new engines.

These ships were troubled by their new electric-drive systems and occasional brown outs and black outs.

The ship is the latest of her class – after HMS Dauntless and HMS Daring – to go through the Power Improvement Project (PIP), a move towards replacing original diesel engines with more powerful cleaner generators.

What I want to know is who failed to clean those stickers off the control panel.

But can it breathe fire?????

HMS Diamond and US warships repel largest Houthi attack to date in Red Sea

HMS Diamond destroyed seven one-way attack drones heading for her and commercial shipping in the area.

Close enough for me.

Nice, going from 2 x Wartsila W200-12V to 3 x MAN 20V4000s is a nice boost to installed power (and reliability). Apparently the French-made W200s have had known issues in the Marine world.

I am not sure why anyone buys Wartsila engines anymore after decades of them crapping the bed.

So in comparison to a car engine that would be like a slant six in a Charger?

Or the Ford 6.0 powerstroke…

Their big cross head 2-stroke designs rock, but the ‘smaller’ medium/high speed engines are renowned for being unrenownable…

Had a MAN 12V4000 Stby genset at one of my past places of work, and that thing was a beastly musical instrument!

OK got it. So its not a Hemi?

So they have gone from 2x 2400 kW developed (4800 kW) to 3x 2000 kW (6000 kW)? A 25% increase in power and a redundant generator?

I believe the T45’s W200-12V were rated at 2100kW and the new MAN 20V4000s at 3200kW, so your numbers are upside down. It’s 4200kW upgraded to 9600kW, give or take, which jives with RN correspondence noting an increase of 5000kW.

So a 130% increase in DG output.

…and an approximate bazillion% increase in reliability…

Price and kickbacks?
