trying to replace Trident with an alternative nuclear deterrent will likely cost more than retaining Trident unless the UK is willing to seriously dilute it's commitment to a continuous deterrent presence (which might be an option to be honest). Defence cuts (which are very likely) could affect the Army and RAF mostly with the Army being reduced to it's smallest size since the Boer War (a kind of pointless comparison though to be honest).
The French and US Navies have been conducting some joint exercises involving French Rafales landing on a Nimitz aircraft carrier and also one having it's engine removed and refitted on the US carrier to demonstrate interoperability. USN Hornets also performed landings on the Charles de Gaulle. Meanwhile the USN is asking the public for help in trying to find 4 of it's UUVs which it lost contact with during an exercise.
HMS Daring is undergoing 6 weeks of intense training as it is tested by the Flag Officer Sea Training taskmasters who make sure RN warships are fit for action. Though it can't receive the full FOST treatment as it doesn't have a working Sea Viper system yet of course.
