UK’s Ministry of Defence has said it would spend $514 million to upgrade the Sea Viper Air Defence system to shoot down drones over Red Sea. The missile system will be upgraded with updated missiles featuring a new warhead and software update enabling it to defeat ballistic missile threats. The contracts were awarded to the British division of MBDA, a missiles joint venture owned by Airbus, BAE Systems and Leonardo the MoD said. The contracts will make Sea Viper the most capable naval air defence system ever developed for the Royal Navy.
