it's an automatic review
Move along, nothing to see here.
The Nunn-McCurdy law in the US mandates a review of any procurement project and a freeze on investment, if the original budget is predicted to be exceeded by over 50% (regardless of reason). The review then has to justify if the need still is worth the money, this has happened to several programmes for example
C5M projct was reviewed and not cancelled
ARH70 was (I Think twice) reviewed and then cancelled
VH71 is just another.
The reason for the increase in costs is dealt with in posts 3 and 4, remember the contract is with LM not AWH.
