Canada's navy is waiting to hear back from the U.S. regarding the purchase of $125-million worth of torpedo refit kits so it can properly arm its four Victoria-class submarines.
At the moment, none of the British-built diesel boats is capable of firing the navy's stock of torpedoes.
Any sale of American made military equipment to a foreign government must be approved by Congress.
Paul Ebner of the Defence Security Co-operation Agency, the office that oversees clearance for such sales, says if there are no objections over a 30-day study period the sale can proceed.
In a news release issued March 23, the agency noted that Canada would have no difficulty absorbing the conversion kits into its inventory.
Of the four Canadian subs, purchased at a cost of $750-million, only HMCS Corner Brook is currently operational as the others undergo various levels of repair.
