HMCS Bras d'Or (FHE 400) Possible Armament

[MechCommander]

Hello, although this hydrofoil was never fitted with any weapons during her time with the RCN between 1968-1971. Given her intended role as a Anti submarine warfare vessel and weapons of the time, what could the HMCS Bras d'Or be armed with?

Here my suggestion on what could be her armament.

2 Mk 10 limbo mortars.
1 3"/50 caliber Mk 22 76mm gun on a duel mount.

What's you suggestions for what she could have been armed with if she was put into a combat role.
