Could Type 45 destroyers receive ExLS in place of the Sea Ceptor arrangement from Type 23 frigates to enable CAMM-ER, if politics were no obstacle?
Short answerIt is technically possible if money and politics are ignored, but extensive structural work on aging hulls can become so expensive that building a new ship is the better investment.
NotesThe proposal is to use ExLS for CAMM-ER on Type 45 destroyers. The reply accepts the technical possibility if money and politics are set aside. A more ambitious conversion could even cut the hull and insert additional structure for Mark 41 VLS capacity. That scale of intervention would still leave questions about the hull's remaining life. A major rebuild could cost more than a new ship, so physical feasibility alone does not establish that the conversion would be worthwhile.
