Guns
As the ship's gun mounts differed from those of her 2 sisters (which had P IV** mountings), the particulars for Fearless are recorded here on her ship's page.
Ten (possibly just eight) 4-in B.L. Mark VII guns on P VIII mountings which could elevate 15 degrees and depress 10 degrees, but though the sights could match the 15 degree elevation, the range dials were only graduated to 14 degrees (11,000 yards). It appears that no other ships carried this particular mount.
These cam-worked sights had range dials for 2750 fps, and 1-in and .303-in aiming rifles. MV could be corrected by adjustable pointer through +/- 150 fps.
The deflection gearing constant was 59.79 with 1 knot equal to 2.41 arc minutes, corresponding to 2750 fps at 2000 yards. Drift was corrected by inclining the sight bracket 2 degrees.
The layer's sight line was 12 inches above the bore, and 22.3 inches left. The trainer's sight line was 12 inches above and 18.25 inches right.
In addition to the MV corrector, the sight had a temperature correcting scale plate and a "C" corrector.
These were F.T.P. sights.
There was an open sight on both sides. No mention is made of a free sight.[1]
Battle of Jutland
Fearless led the First Destroyer Flotilla, attached to the Battle Cruiser Force.[2]
Fire Control Instruments
The ship may have been equipped with Vickers F.T.P. Mark III equipment for sending range and deflection to the guns, as was her sister, Active.[3]
Captains
Dates of appointment are provided when known.
- Captain Charles Little, in command at end of war.
