In May 1993, a contract for four E-2T (T standing for Taiwan) was signed between the US and Taiwan. It had been announced that these E-2T would be rebuilt E-2B fitted with AN/APS-138 radars. The first two E-2Ts arrived in Taiwan by sea on 3 Sep 1995, followed by the second pair on 23 Sep 1995. Although the four E-2Ts all have E-2B Bureau Numbers, ROCAF officials claimed that they were in fact all new-built Hawkeyes, with only few E-2B parts used, so the aircraft is equivalent to the E-2C Group II standard, with the more advanced AN/APS-145 radar. The aircraft belong to 2nd Early Warning Squadron.

On 13 Jul 1999, the US DoD announced a sale of two E-2T Hawkeye 2000s to Taiwan. The first of the two Hawkeye 2000s was accepted by ROCAF officials at Northrop Grumman's St. Augustine facility on 10 Aug 2004. The second Hawkeye 2000 was received in October. Both aircraft, serialed 2505 and 2506, were transported to Taiwan by sea and arrived on 19 May 2005. The aircraft are assigned to the 2nd Early Warning Squadron at Pingtung-South. This 2506 was seen in its hangar at homebase Pingtung-South.
