If they even still work. The UK has a higher military budget than Russia with a much smaller armed forces and nuclear arsenal to maintain and a Trident whistle-blower a few years back leaked evidence that the UK's nuclear deterrent was so dilapidated that not only could they not test fire the missiles, they couldn't even do the test to show they could test fire them.
Final tests - At the end of a patrol tests are done to see if the weapons system could have performed a successful launch. These tests let us know if we really were providing the UKs strategic nuclear deterrent / CASD. It had reached the end of my three month patrol. It was time to do WP 186 missile compensation test. The test was carried out 3 times and it failed, 3 times. Basically the test showed that the missile compensation system wouldn't have compensated for the changes in weight of the submarine during missile launches. Which means the missiles would've been launched on an unstable platform, if they decided to launch. Another test was the Battle Readiness Test (BRT) which proves that the muzzle hatches could've opened whilst on patrol; if they needed to launch, they could've launched. The BRT was cancelled due to the main hydraulic system containing mostly sea water instead of actual hydraulic oil. Basically they're endangering the public and spending Billions upon Billions of tax payers money for a system so broken it can't even do the tests that prove it works
I imagine most of Russia's nukes are sitting rusting in bunkers or on broken down mobile platforms.
Most of the high technology modern weapons they showcase on TV have extremely limited numbers and often aren't even combat operational. They're for show.
