Seaweed said:Besides Inclining Experiment, plotting turning circles so as to calculate advance and transfer, speed trials etc there is all the setting to work TOGETHER of the various components of the armament (what used to be called HATS and SATS), magnetic signature, does the prewetting work/cover everything, ...but it's a bit of a puzzle why this should take longer than six months.
You would be surprised I can remeber doing part of first of class trials 3 years after the boat was commisioned, and we were secoond of class. Every boat/ship has hast and sats, they are the bit about proving the boat was built by the builder as per contract. The first of class involves a lot more where both the ship and it's systems are fully characterised. For example for the fire control system hats and sats will simply confirm it works to the spec, in first of class trials they will stretch the system a to see how much better than spec it is, whether it can achieve performance in areas not covered by the spec. For example I understand that during first of class trials they discovered sea dart had capability outside that requested in the spec and this became of value later in the system life leading to further development and improvement of that capability.
