This was not always possible however, as Types 271 - 274 were already in use for original centimetric sets, thus some metric sets in the Type 28x range had 20 subtracted (e.g. the metric Type 282 was replaced by the centimetric Type 262). Aerial outfits were given a three letter identifier that began with "A".

Originally known as Type 271 Mark V, this was a significant improvement on the original design and was later renamed to make this clear. Used a single transmit/receive antenna, waveguides instead of coaxial cables and a much more powerful magnetron that considerably improved all-around performance.

A version of the 271 with a much larger 3 foot (0.91 m) diameter full-parabolic antennas instead of the smaller clipped "cheese" antennas of the 271. The antennas were mounted on a stabilized mounting and placed high on the mast on cruiser and battleship sized ships. The larger antennas more

This set also had a secondary surface search function along with aerial and surface gunnery capability and used a
Precision Ranging Panel. The Type 281 ranging system allowed the user to select either a 2,000 to 14,000 yd (1,800 to 12,800 m) or a 2,000 to 25,000 yd (1,800 to

The
