How long would it take to convert a large container ship into an anti-submarine helicopter platform?
Short answerA useful British conversion might take about a month, but the time depends on whether it must merely land helicopters or sustain a full squadron.
NotesA basic deck for a few helicopters could be assembled quickly from prepared modules, but sustained squadron operations require aviation fuel, maintenance support, and extra accommodation. British stocks of containerized equipment could support a useful conversion in roughly a month. The comparable US estimate was six or seven weeks because greater resources would be offset by a more bureaucratic process, although existing ships could shorten the work. Readiness depends less on the bare hull than on having the aviation support package already designed and available.
