If you are not aware, the RAF over the course of the next few years are planning to replace the fleet of  81 T1's with a smaller lot of only 28 T2's.
Now, a little bit of background to this subject. Hawks are used as a training aircraft across the services train fast jet pilots, all of this is done at RAF Valley. The Hawks are also used to 'play the enemy' to let front line squadrons practice, and this is done out of RAF Leeming. Finally, the Hawk is used by the RAF Centre of Aviation Medicine as a test bed for their research, their jets are the only ones in the RAF allowed to pass 9G in testing.

Having said this I would put all the roles, other than the Centre of Aviation Medicine, in a critical category which as a result needs keeping. I believe 100 squadron at RAF Leeming will remain unaffected and will simply receive new Hawk T2's once its current T1's reach retirement. The training role within the RAF is currently being reduced quite considerably, and so I believe the 28 Hawk T2's currently at RAF Valley are all that will be used, along side the replacement of the Tucano's for Pilatus PC-10's, also in much smaller numbers. The RAF centre of Aviation Medicine will use a simulated of some sort rather than requiring its own flight of fast jets.

In terms of capability the T2 is a completely different being to the T1, the T2 has complete LED screens as you would expect from a modern day fighter, whereas the T1  remains still back in the 1970's, also a change in engine to the T2 to the more Rolls-Royce Adour 951 engine. These changes make the T2  what the T1 was in its day, so all in all the change simply brings the training fleet back to the modern day but in a smaller numbers. 
Arguably it has just got to be accepted that the numbers of jet fighters will reduce in the coming years and there is no longer the requirement for a large training programme for new pilots and that is what we are seeing with the relatively small number of Hawk T2's ordered.
