Well the Type124 ASDIC will come as stock equipment next event from the Royal Navy DD.

Until then, other than the previous ranking reward it is only available via this limited-time saury mini-event quest.

The Quests that gives TBF as reward are permanent quests that you can do at any time as long as you meet the requirements. Statwise the Tomonaga/Murata are better and the TBF is actually only used for the Conversion quest to obtain TBM-3D.
