Final preparations done and the hall is set up for the 2026 RUSI Military Technology Conference. Hopefully we will see many of you there today. If not: you are missing out!

A great series from @triclassified covering the awful consequences of Philby's actions, as well as the sometimes farcical nature of the whole affair.
He's back. MI6's greatest traitor returns to @triclassified podcast as we finish the story of Kim Philby. We pick up with him in Washington as liaison to the new CIA. Episode 1 includes possibly the worst dinner party in history when old friend Guy Burgess drops by......

RUSI was pleased to partner with @CSIS and @UKinUSA yesterday for a conversation with UK Defence Secretary @wesstreeting (@DefenceHQ) on the future of US-UK defence cooperation.
As Europe rearms and transatlantic burden-sharing evolves, the discussion examined how London and Washington can keep deterrence credible.

Even worse, in practice it is not operating at speeds remotely near the new velocity restriction that suddenly came into effect last night.
“Starlink terminals used by Ukrainian drone units began experiencing signal failures at speeds above 160kph, disrupting several missions early on Wednesday morning, according to military personnel and senior Ukrainian officials.
‘Logistics at the frontline and middle strikes are badly limited,’ one senior Ukrainian official familiar with the situation on the front told the FT. Ukraine’s middle strikes target Russian military supply lines and logistics. The limitations came with ‘no warning, just in the middle of the night’, the official said.”

@jpanikoff and @MTSavill joined @AKendallTaylor and @jteurope on Brussel Sprouts this past week to discuss if and how the Iran war would spread to the European territory and how prepared NATO is for a response.

Ken McCallum, DG of MI5, gave his annual threat assessment today. Announces a new AI Threat Assessment Centre, or AITAC.
"Not yet realised – but the misuse case to which I’d attach greatest weight – is AI’s potential to change the stakes on existing or even new bioweapons."
Thought-provoking latest Net Assessment podcast from @profmarlowe @RealChrisPreble @ZackCooper on the potential impact of AI. Worth also reading the recent blog by @kpd_musing on scenarios and predictions for the scale of such disruption.

Great to be on board @marmilbr training ship ‘Brasil’ this evening with my wife. Brazilian food remains undefeated!
I also learned a lot about the Marinha do Brasil, I promise!

Pretty sure I didn’t do any of this @DefenceGeek, and I still got blocked…🤷🏻♂️
A privilege to be on @CNASdc Brussels Sprouts for the first time, and a good conversation; I’d be interested to hear if others think we characterised the threat and frictions accurately.
Thrilled to have the opportunity to join the @CNASdc Brussels Sprouts podcast hosted by my friend and former USG colleague @AKendallTaylor and @jteurope. And to get to engage on such an important topic alongside @RUSI_org's @MTSavill. You can find the episode here:

@AtlanticCouncil
A good discussion on an important subject, given the occasional hyperbole, but also the real need to improve our defences against air attack. Israel and Ukraine as instructive, but the UK's geography means the threat would be slightly different.

This was great to discuss with @MTSavill and @gregbagwell for @bfbsSitrep
As well as more recently highlighting the offensive part of air and missile 'defence'. telegraph.co.uk/news/2026/03…
And @Sidhart94353129 produced comprehensive analysis last year on the approach the UK could take to sequentially upgrading defences, given the enormous costs and need to prioritise.

Important discussion between @RolandOliphant and @c21st_sailor and @Sidhart94353129 of @RUSI_org on Iran The Latest. US military superiority over Iran does not mean there aren’t costs to this scale of operation.

Being a great cultural institution the Imperial War Museum gets its share of brickbats - here's what I learned in eight years on the board markurban.substack.com/p/sec…

"Russia cannot simply build its way out of the problem through numerical expansion." New RUSI research by Dr Sidharth Kaushal finds Russia's nuclear modernisation will favour response speed and precision over mobility and arsenal size. It will see continued investment in silo-based systems, theatre-level strike capabilities, and counterspace tools, while mobile launchers and submarines see less growth, treated more as a retaliatory hedge than the centrepiece of deterrence.
