Russian Defence Ministry said its air defences shot down a "long-range combat tactical missile", seven guided bombs and 602 fixed-wing drones in the past 24 hours, but did not identify the missile model or provide further detail. Ukraine has not publicly confirmed use of a ballistic missile. Ukrainian defence firm "Fire Point" has said its FP-9 ballistic missile, with a reported range of about 850 km intended to strike deep Russian targets, could begin flight tests after engine development is complete as soon as this summer or early autumn.

Naval Air Warfare Center Aircraft Division is piloting a 3D-printed composite-patch repair that halves F/A-18 Super Hornet composite repair time by allowing high-performance patches to be applied directly to the airframe. The method, which passed lab tests and is scheduled for trials on active aircraft this summer, lets forward bases perform complex repairs without highly specialized technicians and avoids long delays from sending parts back to home maintenance depots; 22 naval maintenance sites already have 3D printers. The push runs alongside the US Marine Corps’ transition to F-35s, with all Super Hornet squadrons planned to retire by 2030 — a shift that will remove related maintenance specialties — and, if widely adopted, the technique could speed and add flexibility to frontline naval aircraft maintenance.
