T45 Abm
Tourist, I will! If you think there's money in the MoD's budget to leverage Aster/Sampson to ABM capabilities, you must know something the rest of us don't! The first T45 won't have even anti-air operational capability for another 2 years.
Arliegh Burke, F100, Dutch LCF and German F124 are also Air Defence Destroyers but retain significant ASW capabilities. An AB also carries a fair number of TLAM's.
