USS Block Island (CVE-21) underway, 12 October 1943, wearing Ms.22 camouflage. Note that she is now fitted with SK air-search radar instead of the SC set. The smaller system at its top edge is IFF (Identification Friend or Foe), not a radar as such but an interrogator compatible with the beacons installed in aircraft. The pole mast forward of the island is topped with HF/DF (high-frequency direction-finder, or "huff-duff"), which enabled ASW to be effectively prosecuted since the carriers could pick up and establish the bearings of U-boat communications.
