Sitrep’s Simon Newton has just returned from Ukraine - he reports for Sitrep from a drone testing centre where new models are trialled before being used in combat.

Sitrep also hears from the former Champion Boxer, and now Mayor of Kiev, Vitali Klitschko, on his country’s will to resist.

Also on Sitrep, as tensions remain high in the Middle East, Britain deploys a Type 45 Destroyer HMS Diamond to the Gulf and America sends the USS Eisenhower through the Strait of Hormuz. 

Sitrep looks at how Aircraft carriers are used to deploy both hard and soft power and hears from the Commanding Officer of the UK’s biggest warship HMS Prince of Wales.
