Yes to everything except questions in House. Although it was pointed out to MoD that there already had been questions in the late 90s (in a positive sense, when a wider use of the technology was anticipated). Had they simply Googled, the Hansard entry would have shown them the DTS was 10 years out of date (for that particular technology). The PQ even asked how much R&D, plus full production and embodiment had cost. (A fifth of the more recent R&D estimate). If you set aside far too much, even if it is needed, that means the funding is not available elsewhere.
You'll have gathered I'm not spilling any beans - it is a case of collating known facts and understanding the linkages. The original PQ arose from an article in Jane's.
Not unusual to destroy tooling that will never be needed again, but retain the original research work. The latter forms the baseline for the upgrade and one needs to maintain an audit trail.
