[3] On 12 January 1968, Bayandor was dispatched to Greater Tunb, in response to British-encouraged flying of the Ras Al Khaimah flag at the island.

[13] According to Anthony H. Cordesman, "weapons control, search/track radars, and sonars have not been fully modernized since the mid-1960s, although some aspects of the electronic warfare capabilities, communications, and battle management systems in the Bayandor seem to have been upgraded".

[11] On 20 January 2016, the 38th naval group comprising Bayandor, the replenishment ship Bushehr (422) and the landing ship Lavan (514), left home for a multi-purpose anti-piracy, flag, intelligence collection and training mission that included crossing the Bab-el-Mandeb for a voyage to the Red Sea, as well as crossing equator for a port call to Dar es Salaam, Tanzania on 1 March 2016.

[11] Along with her sister Naghdi and the amphibious ship Tonb (513) of the 50th naval group, she decked at Colombo, Sri Lanka and Mumbai, India during another multi-purpose anti-piracy, flag and training mission.

[11] As part of the 60th naval group with Lavan and Bushehr, between 20 January and 16 March 2019 she sailed 5,600 nmi (10,400 km) in the Arabian Sea for anti-piracy operations and then made another visit to Colombo.

[11] Bayandor made security patrols in the Arabian Sea and Gulf of Aden and between May and July 2019, navigating some 2,350 nmi (4,350 km) in the same formation of vessels, this time as the 62nd group.
