Astute will already have a larger torpedo room than Virginia (36 weapons vs. 26) and more horizontal torpedo tubes (6 vs. 4), so the net warloads are about the same (36 vs 38). BAE and the MOD have never absolutely ruled out VLS tubes for the later Astute's (ie Batch 2 onwards). The main driver for fitting VLS would have been if it proved impossible to economically adapt the new Tactical Tomahawk LAM for horizontal torpedo tube launch.
