The “零式艦上戦闘機” (or, “rei-shiki-kanjō-sentōki”) is better known to the rest of the world as the Mitsubishi Zero. The first image is the intact Zero brought back from the Aleutian Islands in 1942. It is seen here at NAS North Island in that same year. The second image is of what I assume to be a different aircraft some six or seven years later at NAS Whidbey Island.
I was quite surprised to find this photo showing a Zero still around well after the war. It is at least 1948: There are P2V Neptunes in the background as well as an R5D coded “RS” of VR-5. That tail code entered service in 1948.
