Mazut, that's the stuff, just found the original article I read

How much heavier is that that the usual stuff commercial ships use?
I get the impression the biggest difference is the quality control just isn't there, whereas IFO 380 etc is quite tightly defined, catalyst fines, viscosity, russky mazut appears to be whatever they can get to run out the bottom of the fractionation tower with a bit of encouragement as opposed to chiselled out and removed with buckets. https://www.businessinsider.com/russias-admiral-ku...

Most military stuff runs on gas turbines for speed, or diesel for endurance, the diesels can take fairly heavy stuff, but the gas turbines need a fairly light fuel, the gas turbines in the Type 45 for example are based on the RB211 that powers 747's and needs a fuel that can be fairly easily atomised. Kuznetzov has boilers and steam turbines.
I think a lot of civilian ships tend to run on heavier fuels due to the high energy density, but there's been a move away from it in recent years due to pollution concerns. However I suspect there's a few maritime engineering types on here who know way more about it than me.
As hidetheelephants mentioned, that mostly went away with IMO 2020 regulations.

I went out Sunday morning on a friends boat to get some action shots of our local lifeboats during their training exercise alongside the coastguard helicopter. They were practicing winching someone to and from the helicopter while underway - very, very cool to watch!
Say what you like about Old Harry, he rocks!

Amazing that only 20 years after that photo was taken the French had ships made entirely of steel, with steam engines and large calibre breech loading guns on swivels.
Their problem was that they had the hull design blueprints upside down and couldn't stop because they'd be found out and embarrassed and just built on top of the little space they had left.
