UK unveiled three prototype long-range cruise missiles for Ukraine under "Project Brakestop", all deliberately built with zero US components, so the UK has full sovereign control over exports and Ukraine's use, with no American veto on targets or timing.
Crossbow (MBDA UK), TigerShark (MGI Engineering), and a propeller-driven design (Rotron Aerospace).
Specs: 500-600+ km range, 200-300 kg warhead, 600+ km/h, around £400k each (much cheaper than Storm Shadow), aiming for 20+/month production.
This is separate from "Project Nightfall" (UK's ballistic missile program). Goal: give Ukraine a cheap, mass-producible, jam-resistant deep-strike weapon free of US export restrictions.
