The Avenger Strike Fighter is used for high-speed low level ground attack missions. This makes it ideal for attacking armoured vehicle formations and high-value strategic assets such as munitions dumps. Compared to other Imperial Navy aircraft of its size, it is equipped with more weapons and munitions.
The Avenger is an ancient design, believed to originate on Ancient Terra sometime during the Age of Strife. It was adopted by forces loyal to the Divine Saint Sebastian Thor during the bloody wars of faith and schism now called the Age of Apostasy. Its effectiveness is such that it is now a staple of any Imperial Navy air support mission, holding a glamour of holy import in the wider Imperium. The Avenger is often specifically requested by the Adeptus Sororitas should they require close support in their purgations.
