The UK sent Ukraine an improved model of the Brimstone 2 laser-guided missile with twice the range of the previous design.

 This is reported by The Telegraph.

 The Ukrainian military has converted the trucks for use as mobile launch platforms to destroy Russian tanks and other vehicles from long range. Missiles are usually launched from the air.

 These missiles, along with similar anti-tank weapons sent by Ukraine's other Western allies, could have played a central role in quelling Moscow's military offensive in recent months.

 Britain first transferred Brimstone missiles to Ukraine about six months ago. However, a video released last month by the British Armed Forces Broadcasting Service showed a more advanced version being prepared for transport at RAF Brize Norton in Oxfordshire.

 The missiles, which cost around £175,000 each, are either laser-guided or can select their own target from a pre-programmed list using ultra-high-frequency millimeter-wave radar.

This system allows the weapon to scan the battlefield and select the most suitable target, neglecting civilian vehicles or less important military equipment.

 When guided by a laser fired by friendly forces, the Brimstone can be used in built-up areas with great accuracy, limiting the potential for collateral damage among civilians.

 The first version of the Brimstone entered service with the Royal Air Force in 2005. In 2008, it was upgraded so that it could be guided by a laser. Brimstone 2, the next improved model, entered service in 2016.

 With a jet range of about 60 km and a warhead weighing 6.3 kg, the Brimstone 2 is designed primarily to engage ground targets, including moving vehicles.

 However, a naval version of this weapon was developed, specifically designed to defeat fast attack vessels such as speedboats. It is very similar to the previous options, but must compensate for radar and laser "scattering" that may occur when working over water.

 In 2013, the Sea Spear was tested with a simulated order of battle of five targets, one of which was a 15-meter vessel moving at a speed of 20 knots.

 The successful test demonstrated the missile's ability to hit multiple single targets at sea.

 During a visit to Kyiv at the weekend, Rishi Sunak announced the provision of another package of military aid to Ukraine in the amount of 50 million pounds.

 Brimstone is not believed to be part of that package, which is instead focused on providing weapons and ammunition to counter the Iranian drone threat.
