Through-Life Costs. The Study assumed a force of five conventional

mono-hulled replacement vessels would be required for a 25-year life

cycle. The following Through Life Costs relate to a medium speed

Patrol Craft with a complement equating to the present TON vessels and

with normal refit, maintenance and operating patterns:

(1) Procurement

-

£18M

(2) Operating costs.

-

£56M

-

£23M

NOTE:

(3) Maintenance

TOTAL (over Life Cycle) approx. £100 (at Sept 77 prices)

These figures relate to the craft costs only (weapon equipment

procurement/through life costs are not included).

f. Availability. The Study was not able to differentiate between

the availabilities of the various conventional Patrol Craft designs

submitted.

A general figure of craft available for patrol duty for

70% of the year was used for all craft evaluated.
