Hobart, Type 45, and Arleigh Burke illustrate the long interval between destroyer design decisions and operational ships. Hobart's Spanish parent design and Type 45's route through Horizon are traced to the breakup of NF-90. A planned service life of 25 to 30 years brings rising operating costs as a ship approaches replacement. Allowing roughly 15 years to deliver a British successor makes a 2026 start late against the 2036 date used here. The estimate of 2038 or later is a personal suspicion based on the pace of Type 26 construction, rather than a confirmed replacement schedule. The comparison treats Virginia, Astute, and Collins replacement needs as a precedent for collaboration across the three navies.

Hobart, Type 45, and Burke replacement pressure
AUKUS timing is tied to aging air-defense destroyers and the long lead time needed to replace Hobart, Type 45, and Burke-era ships.
