Seventy years in the past, Britain faced a quandary. It sought after to stay a number one army energy however not had the commercial sources to maintain all of the typical functions it had inherited from the second one international struggle.
The answer proposed within the 1957 Sandys defence white paper was once technological. Guided missiles, Duncan Sandys argued, had been reworking war so basically that many conventional functions, together with some crewed struggle plane, would develop into out of date.
In different phrases, by way of embracing this technological revolution, Britain may just succeed in defence at the affordable. Britain’s new Defence Funding Plan (DIP) displays a identical strategic intuition. The applied sciences can have modified however the underlying quandary has now not.
Pronouncing the DIP within the Space of Commons, Dan Jarvis, the defence secretary, mentioned the United Kingdom could be making its “largest ever investment in drone warfare: £5 billion for strike, protector and surveillance drones across the Royal Navy, the Army and the Royal Air Force.”
Listed here are one of the crucial key applied sciences mentioned within the Dip.
Drone ships
No less than 1 / 4 of the £5 billion introduced for drone war goes in opposition to a “hybrid fleet,” a basic re-imagining of the Royal Military. The United Kingdom’s sole ballistic missile defence capacity – the Kind 45 destroyers – will not get replaced by way of a like-for-like. As an alternative, a community of Crewed Fight Vessels (CCVs) will act as keep an eye on hubs for specialized, uncrewed boats.
Those would come with Kind 91 missile barges, Kind 92 and Kind 93 anti-submarine and underwater surveillance platforms, and Kind 94 radar vessels. In theory, distributing the sense, come to a decision and strike purposes around the army provides a number of benefits.
It might ease persistent staff shortages by way of lowering workforce necessities, lengthen radar and sonar protection over a much wider house, and make the fleet extra resilient by way of dispersing struggle energy fairly than concentrating it in a handful of pricy warships.

Uncrewed vessels may be rearmed or maintained independently and with out the
design constraints of supporting sailors at sea. On the other hand, the demanding situations are important.
The DIP envisages this idea changing into confirmed and operational sooner than the Kind 45 retires within the mid-2030s, even though resilient communications and digital war coverage for independent warships stay immature.
Neither is Ukraine’s use of naval drones a simple template. The Royal Military’s fundamental duties – specifically anti-submarine war within the Top North and North Atlantic – are way more hard than Ukraine’s use of maritime drones within the Black Sea.
Whilst experiments reminiscent of the usage of RFA Lyme Bay as a mothership for independent mine countermeasures (together with drone minesweepers) are encouraging, retiring Britain’s simplest ballistic missile defence destroyers sooner than the broader structure has been confirmed would entail important operational chance.
AI focused on community
The military’s Challenge Asgard illustrates the similar technological philosophy in a distinct area. Asgard objectives to grow to be how – and the way temporarily – the military identifies and moves objectives, by way of linking sensors, armoured cars, drones and long-range guns right into a unmarried, AI-enabled focused on community.
First trialled in 2025, Asgard is now receiving £370 million to broaden an operational capacity, reflecting the Military’s ambition to succeed in a tenfold building up in struggle energy basically via automation fairly than expanded forces.
This concept has crucial highbrow historical past. All over the Nineteen Nineties, america championed the idea that of network-centric war: the proposition that awesome data sharing would permit smaller, extra agile forces to defeat numerically awesome combatants. However Britain was once quickly involved concerning the affordability and technological problem of making such extremely attached forces, adopting as a substitute a lighter model: network-enabled functions.
The DIP means that the federal government now believes the expertise is catching up with the speculation. However outdated weaknesses stay. Networks simplest paintings in the event that they live to tell the tale. Communications can also be jammed, satellites disrupted and device attacked, and Russia has the digital war functions that would, with out good enough safeguards, do all 3.
‘Loyal wingmen’
It is usually the case that what has labored at smaller ranges now must be scaled throughout Nato. If it really works, Challenge Asgard would supply Nato land forces having the ability to keep an eye on long-range guns of their very own, lowering their reliance on air forces which is able to want to center of attention on supressing and destroying enemy air defences.
That job is motivating the DIP’s funding in Collaborative Fight Plane (CCAs) – uncrewed platforms that can fly along the RAF’s Typhoons and F-35s.

Those “loyal wingmen” drones would give a boost to crewed plane by way of performing as scouts, decoys, soaking up enemy fireplace or jamming enemy radars. They may well be managed by way of the pilot of the struggle jet, or paintings autonomously.
Techniques such because the MQ-28 Ghost Bat are at an early level of construction. To be militarily helpful CCAs should mix lengthy differ, top pace, low observability, resilient knowledge hyperlinks and significant payloads, necessities that temporarily method the complexity, and doubtlessly the price, of the crewed plane they’re meant to enrich.
Will it’s inexpensive?
In opposition to those demanding situations, the federal government’s headline dedication of £5 billion on those techniques due to this fact turns out extra like a down fee than the entire loan. Unfold throughout 4 years, 3 armed services and products and an exceptionally various differ of programmes, it’s much less transformative than some might consider, and in no way at the timelines some assume are essential as tensions proceed with Russia.
The unit prices of what is going to be specialist apparatus might stay prohibitively dear. Take the hybrid Military for example. The independent techniques in query require resilient communications, refined sensors, digital war coverage and top engineering reliability, that means the mixed value of CCVs and their uncrewed flotillas may just method that of the destroyers they exchange.
Even though the investment can also be discovered – and there are excellent causes to query whether or not it could actually – Britain should nonetheless display that its defence trade can ship this technology-intensive power. Increasing army output calls for way over greater budgets: it calls for further manufacturing facility capability, professional employees, shipbuilding infrastructure and resilient provide chains. That is specifically true for independent techniques whose army worth relies on being produced, sustained and changed at scale.
The DIP rests on 3 assumptions: that independent techniques mature temporarily, end up reasonably priced and can also be produced at scale. The Sandys Evaluation rightly foresaw the missile age however underestimated the endurance of typical forces; new applied sciences reshape war however they infrequently exchange its enduring basics.
If Britain is to wager on autonomy, due to this fact, it additionally wishes the spending profile to make that wager credible. In the end, crucial judgement at the DIP may not be that of long run historians, however of the occupant of the Kremlin nowadays.
