[3] Submarines of the Nagapasa class also possess ZOKA acoustic torpedo countermeasures manufactured by Turkish company ASELSAN.

[5] As part of the deal, two of the submarines (Nagapasa and Ardadedali) were constructed in South Korea, while the third one was constructed in PT PAL's shipyard in Surabaya as part of a technology transfer program.

Thus the Nagapasa was floated on a barge and relocated to Semarang Dock, within the same shipyard in Surabaya, about 350m away, but later returned the submarine to its original yard, where it was launched on 11 April 2019.

[2] The name Alugoro - originating from a weapon name in wayang tradition -[11] was previously assigned to a Whiskey-class submarine built by the Soviet Union which was used during the 1962 Operation Trikora.

[12] Alugoro was reported to have participated in the search for the ill-fated submarine KRI Nanggala[13]
