The ships were built by Yarrow Shipbuilders of Glasgow (now BAE Systems Surface Ships) of United Kingdom based on the F2000 frigate design. Lekiu was launched in December 1994 and commissioned May 1999. Although the Lekiu was launched before the Jebat, but Jebat carries the lower pennant number (FFG29) compared to Lekiu (FFG30) to signify the seniority of this ship, which accommodates the Admiral of the Royal Malaysian Navy. (Hang Jebat succeeded Hang Tuah as Laksamana (Admiral) of the Malacca Sultanate, while Hang Lekiu was never made a Laksamana.).[2]
