Began today’s exercises with a rather good close range shoot at towed sleeve, followed by a 6″ sub calibre blind at a Patt 6 [possibly related to an anti-submarine sonar device] target . The first run of the latter was poor, but succeeding runs were better, the improvement for line being very good. Spotting for range was not so easy as good echoes could not be obtained from splashes of sub-calibre. A very good 4″ HA [High Angle] shoot was carried out during the afternoon, the sleeve being shot down in the second run. Later took part in an RIX with [HMS] Orion, en route to Alex. Anchored in Mex Roads at 1730.
