Canadian Navy Fire Control Systems
*About half way down the page.
Installed on DDE refitted Tribal class destroyers, as well as the refitted ALGONQUIN and CRESCENT for the control of 4"/45 and 3"/50 guns. The Mk.63 system consisted of the Mk.29 gunsight and the SPG 34 gunnery radar system (29 + 34 = 63), and in the case of the Tribal class there were two separate Mk.63 systems installed (one forward, one aft). On the Tribals, the SPG 34 antennas were installed directly on the 4" "B" mounting and the 3" "X" mounting. The two Mk.29 gun sights were mounted forward on the bridge (in the place of the removed director) as well as aft .
