So I've got my Sift interview at the end of this month and medical on the 16th. Like everyone else I'm sure I've searched for all the past questions people have been asked and collated them into one document to prepare answers for. The Bit I'm struggling with is the Navy Knowledge. I've just made a list of all the Ships listed on the Royal Navy website and there's 70 +, Do i need to know the name of all these ships and their roles/weapons/radars as well as being able to identify them? Obviously you've got all the different categories of ships so is it the case that you just need to know a couple in great detail from each category? After I passed my Psychometric test's the officer there gave me an A3 pull out with the silhouettes of around 23 ships from aircraft carriers to aviation training ships, 3 submarines, 6 helicopters and some small arms and vehicles, He told me to learn these so is it the case that these may be the only ones I need to know ? Any help would me much appreciated !
