The Navy has too many responsibilities for too few ships to afford single purpose ships unless there’s a technologically imposed constraint. The Burkes have AN/SQS-53C bow sonars and AN/SQR-19 towed arrays. The Flight IIA and Flight III hulls carry MH-60R helos.
122 P-8 are planned with production of parts for the 11th lot already underway. They’ll be supplemented by BAMS — the MQ-4C Triton (naval Global Hawk) in the surface surveillance role.
