The Navy E-27 Receiver (海軍「仮称電波探知機(逆探)」E-27受信機) was a Electronic Support Measure (ESM) Radar Warning Receiver (RWR) based on the Metox RWR brought back to Japan during the Submarine Dispatch Operations to Germany (遣独潜水艦作戦).
- Various Japanese submarines were equipped with German RWR's:
- On 6 August 1942, I-30 was fitted with Metox when she was moved to one of the U-boat pens in the Keroman Submarine Base, Lorient, France.
- On 20 August 1943, Metox was installed on I-8 by the tripulation of U-161.
- On 5 December 1943, I-29 was equipped with the Metox installed on I-8. Later on 14 February 1944, the tripulation of U-518 installs the newer Naxos and Wanze RWR's on her bridge.
- On 22 June 1943, I-52 was equipped with Naxos by the tripulation of U-530 before being sunk on the night of 24 June.
- On July 1943, Yamashiro was used to test a prototype version of the E-27 Receiver. The tests were met with success, thus 800 units were produced by Spring of the following year and 2,500 units by the end of the war.
- Prior to Yamashiro's tests, on 1 June 1943, Yukikaze was equipped with an RWR prior to the Battle of Kolombangara.
- The E-27 was equipped on the I-400-class and Ha-101-class submarines, among other vessels.
