Some early development work has been *°ne at both the firms' and Govemment ^| e and British Aerospace have very recently offered a fixed price developm ^j^ d production contract at a ^ta l cost of £291 million for 750 missiles and Jj ^ illio n for 1,000 missiles Compared with their earlier offer of £388 millio TO^ 50 missiles and £426 **io n for 1,000 missiles). The contract would pro p e r enough missiles to thieve an initial operational capability to be delivered by August 1987 and for liverie s to be complete by September 1989. Failure to deliver the firs t 100 ^ssiles on time would render British Aerospace liable to liquidated damages of ^ to £0.4 million (a similar premium would be payable b ^VU toistr y at M defence for early delivery). ^B^^ . ^certainties 7 - The choice of missile is complicated by a number of uncertainties ^Q|se a «ect delivery and operational capability, final cost and export pptential ^ ^ M I | SECRET ] L_ H 1 SECRET H H \ I X^ Sharing the order between HARM and ALARM would be the most expensive H |f ^ ^ o f an. and we have not considered i t further in this paper. H Pgllyery and npprational Capability ^ V \erican s ^e^rate d that HARM works, but the missile will \ not necessarily be capable of dealing with improvements i n Warsaw pac H defences i n the 1990s without itself being improved. ALARM is as yet developed, but the concept is more advanced than HARM: i t incorporates the latest techno* * particularly i n software, and would therefore be more readily capable of being enhanced to deal with improvements i n Warsaw Pact ^fences in the 1990s (although there must also be some uncertainty as to how ^e threat develops ljffca t will be needed to meet it) . We should be able to ^velop- i t to meet oS* & requirements and should not be dependent on improvements which the Americans might decide to introduce in HARM. H 10. But there must be a aue j^mar k over the ability of British Aerospace • « * its sub-contractors to develop; ALARM to an acceptable standard i n the *°ur years which they have allowed. Past experience of weapon developments, hoth m th e Unit e d Kingdom and the I (to d States, suggest that a six-year development programme would be UV realistic . The contractor s development plan is based on optimistic assumptions and allows virtually no t^ e for the solution of any serious probl t^ ^ arise. There is a risk o ^ e slippage in deliveries. This has to l^ he d against the financial ^eentive on the firms to deliver on time andf A d to supply the RAF with operationally fully acceptable weapon. I f neve TOt e delays occurred and the RAF had to face a conflict without an adequa ^ apon , i t would take betwee n 6 and 12 months, assuming full United States co-operation, to adapt H the RAF Tornado to operate HARM. On final cost the ALARM programme on the face of i t has ^fi^ er degree H o f certainty than HARM, since 97 per cent of the work would be on a tixed P^ice basis subject only to increases due to inflation. As is usuaT ^ rsuc h arrangements, i t is the contractor who would be liable for all ui8 ^J| u i c <*t caused by delays or failures on his part to meet the agreed programme t^s could cost him up to £3 milion for every month overrun. *V*^ H ^^^^ | SECRET | 1££^B \ ) SECRET H IH Va^ospBce could be expected to exploit every opportunity to overturn the feed contract, but the Ministry of Defence would be obliged to meet additional Sflfo . and only if, delays arose from Government failure to provide trials or jfi L facilities. The Ministry of Defence regard British Aerospace's new offer ^^ eptabl e from a contractual point of view. I t involves the company absorbing development and production costs at a saving to the Ministry of Defence of £97 million i n return for a higher unit price to the Department for any missiles bought beyond the original 750. The effect is that the cost is reduced by compa*pn with the previous offer i f less than 1.620 missues are bought and increased i f the total purchased is higher than 1.620 (though the ^fe r does nottaS^commitment by the Ministry of Defence to buy more M 12. The final price of HA *L io t within our control, since we should have to • ^ the same price for th^W g -head , which would be manufactured in the United States, as would be pa^ the United States Forces themselves.

The cost differential between HARM and ALARM is also subjWWtuations in the real, exchange rate o f th e pDun d against the dollar.
