The Beowulf System Defense Force (BSDF) was the naval component of Beowulf's military.
In its capacity as the spacefaring military of Manticore's staunchest ally in the Solarian League, the BSDF was kept routinely up-to-date on the latest Manticoran military developments. However, in quiet agreement with the Royal Manticoran Navy, the BSDF refrained from introducing Manticore's newest technologies into their own warships to prevent them from finding their way into the hands of the Solarian League Navy. The BSDF as well had refrained from providing any observers to the Manticoran-Havenite Wars. (HH12)
