Any pirates or mercenaries attempting to prey on the quarian flotilla must contend with the Heavy Fleet's cruisers, frigates, fighters, and carriers. The Heavy Fleet is led by Admiral Han'Gerrel. The admiral firmly believes in the importance of ship maintenance and regular training exercises, and actively encourages those on pilgrimage to seek out technology that will upgrade his fleet's capabilities. As a result, cutting-edge technology is often found in the best of the Heavy Fleet's vessels.
