Matthew Savill @mtsavill.bsky.social · 11/06/2026There's plenty more in the article, but it takes a cynical tone because the delay does not bode well for the type of change and ambition set out by the SDR, and matched against the government's own rhetoric. 060
Matthew Savill @mtsavill.bsky.social · 11/06/2026Spending tricks/honesty: as well as the profile and CDEL/RDEL issue, is the DIP clear about compromises? And what claims does it make about savings and 'efficiencies'? Past reviews (especially 2015) foundered on optimistic assumptions. 150
Matthew Savill @mtsavill.bsky.social · 11/06/2026Enablers: as well as sexy weapons, what does the DIP say about enabling capabilities and systems, like expanded logistics capacity, information, space-based capabilities, the Digital Targeting Web. If they can't use information more effectively, the Forces won't be more 'lethal' 120
Matthew Savill @mtsavill.bsky.social · 11/06/2026Transformation pace and scale: the SDR was a shopping list. The DIP makes that reality, and what it says about new technology, and the skills and concepts required to make them useful, will something about where we are really placing our bets. 120
Matthew Savill @mtsavill.bsky.social · 11/06/2026Personnel: if 'people are our most important asset', where is money being put on training, terms and conditions and support. If the argument is 'that isn't investment' then we are once again looking at equipment instead of capability. 130
Matthew Savill @mtsavill.bsky.social · 11/06/2026Focus for investment: before buying equipment, can improve the deployability of the capabilities the UK already possesses. Munitions types and stockpiles, logistics, storage, basing, infrastructure all help make the forces more effective. 130
Matthew Savill @mtsavill.bsky.social · 11/06/2026Spending profile and type: when is money being spent; is it all in later years (especially after elections)? And how much is resource (RDEL) v capital (CDEL)? If resources are starved, we are bringing in capabilities and services we can't run or sustain. 130
Matthew Savill @mtsavill.bsky.social · 11/06/2026It appears we aren't getting the Defence Investment Plan today, and it is back to being published 'soon'! Either way, there are some things to look out for and traps to avoid. 🧵 31710
Matthew Savill @mtsavill.bsky.social · 28/05/2026An important point made here by @justin-br0nk.bsky.social: combat power isn't power if you don't have the weapons.
