Typhoons and the warship HMS Iron Duke will deploy to the Baltic this month.
Four Typhoons will take the lead role of the Baltic Air Policing mission which aims to safeguard the safety of NATO partners and wider Europe. Based at Amari air base in Estonia, the crews will operate in a Quick Reaction Alert role.
Defence Secretary Michael Fallon said:
“British planes protecting Baltic skies alongside our warship patrols and troops exercising, show how serious we are about the security of our eastern European partners.
With a defence budget that is increasing for the first time in six years, we can use our forces to keep Britain and our allies safe.”
Later this year Iron Duke is due to operate in the Baltic region with up to four other Royal Navy ships, including HMS Ocean and HMS Pembroke.
