Indonesian Navy Chief Downplays Request to Revive Ageing Vessels

06 October 2020

The Indonesian Navy (Tentara Nasional Indonesia – Angkatan Laut: TNI-AL) chief, Admiral Yudo Margono, has written to the country’s defence minister to explain why it will not be possible to revive a number of naval vessels that have either retired, or are already in the process of being prepared for retirement.

The admiral was responding to a request by the minister, Prabowo Subianto, to either reverse or halt the decommissioning processes of 10 Indonesian Navy (Tentara Nasional Indonesia – Angkatan Laut: TNI-AL) warships that have, or are being prepared for decommissioning.

These vessels are namely the amphibious landing ships Teluk Penyu (513) KRI Teluk Mandar (514), KRI Teluk Sampit (515), the Kapitan Pattimura (Parchim I)-class missile corvette, Pati Unus (384), the troop transport ship KRI Nusanive (973), the oil tanker KRI Sorong (911), the mine countermeasures vessel KRI Pulau Rote (721), the Kupang-class landing craft, Nusa Utara (584), the coastal tanker KRI Balikpapan (901), and the non-commissioned training ship, KAL Kadet-1.

Teluk Penyu, Pati Unus, and Nusa Utara are vessels that have been decommissioned over the past three years, while the rest have been taken out of operational service, and are in the process of being formally retired.

She's planned to sail for at least another 15 years so.....mid life i guess?

She's now just an OPV with advanced CMS and electro optics that's for sure.
I think the first ship of the class has received some upgrades in the past, do they have different parts or common or second ship's upgrade was contracted to another supplier? Even i suppose we have talked about this earlier
I don't quite know,but if a ship has completed 40 years of service, it can hardly be called as mid-life upgrade, it is just an upgrade maybe to extend life or to modernize aged analogue equipments.

I think this class deserves a better upgrade than those ships:

yes, the first of three the Fatahillah (361) have been upgraded already, but it uses different CMS and Electronics

for starters it uses CMS from ultra electronics instead of Catiz CMS from Navantia.
It's also equipped with 2 EO system (Radamec 2500) instead of only 1 (Navantia Dorna) onboard the 2nd one.
I don't quite know,but if a ship has completed 40 years of service, it can hardly be called as mid-life upgrade, it is just an upgrade maybe to extend life or to modernize aged analogue equipments.

well The Van Speijk Frigate used by the navy is already 60+ years, maybe the Navy will extend the operational use of the Fatahillah's till atleast another 20 years+, even though they officially admit to only another 15 yrs.

I think this class deserves a better upgrade than those ships:

Ummm no, those ships are no way suited for Indonesia, it's hull are designed for the calm and Smooth Baltic seas, unlike the South China sea, the Java sea or the waters in around Indonesia. it's electronics are outdated eastern bloc products, and from what I know, many are in a low operational readiness level.
also this.
The Indonesian Navy extensively refurbished their Parchims, to the point where the refurbishing exceeded the cost of purchase. They are still in service

but to be fair some hulls are already upgraded

Indonesia Equips Frigates, Corvette with Stealth Radars

15 April 2014

The Indonesian Navy (Tentera Nasional Indonesia – Angkatan Laut: TNI-AL) will equip a total of four Ahmad Yani (Van Speijk)-class guided missile frigates and one Kapitan Pattimura (Parchim I)-class corvette with low-probability-of-intercept (LPI) naval radars.

The radars will be built by Indonesian naval sensor manufacturer PT Infra RCS, company officials told [i>IHS Jane’s on 11 April.

The company describes its equipment, the IRCS LPI Radar, as a stealthy sea-based X-band (SBX) radar with frequency modulated continuous wave technology.

“It has a maximum power output of only 10 W, making it quiet and virtually invisible to radar warning receivers on enemy vessels”, said Prihatno Susanto, Technical Advisor for the company. “This allows our warships to detect hostile surface combatants without being discovered”.

The IRCS LPI Radar has an effective range of 24 n miles and is equipped with tracking software known as Maritime Tracking Aid that allows for automatic radar plotting aid functionality. The system’s antenna rotates at 20 rpm and has a gain of about 30dB.

The radar is available as a stand-alone system but can also be integrated with a vessel’s electronic chart display and information system (IRCS) and combat management system.

The vessels now equipped with the radar are the guided missile frigates KRI Ahmad Yani and KRI Abdul Halim Perdanakusuma. Both began upgrade works in December 2013. Undergoing the equipment fixture currently are similar vessels in class KRI Yos Sudarso , KRI Oswald Siahaan and the Kapitan Pattimura-class corvette KRI Sultan Taha .




Besides LPI naval radars, the company has also won a contract to equip Oswald Siahaan and Yos Sudarso with naval electronic support measures (ESM) systems that can detect electromagnetic emissions from electronic devices on enemy ships such as radar, communications equipment, jammers and missile targeting systems.

“The IRCS ESM has electronic intelligence (ELINT) capabilities that can pick up signals emitted by hostile warships from up to 90 n miles away via a passive radar”, said Susanto. “Once these electromagnetic emissions are detected, a computer software that comes with the system will be able to identify, classify and pin-point the exact location of the source for commanders to take action.”

The company has indicated that it is currently embarking on an effort to market both systems internationally.


also 2 ships are re-armed with Chine type 730 CIWS the Sultan Thaha Syaifuddin and Silas Papare, replacing the AK-230M

other ships like the Teuku Umar and Sutedi Senoputra are having their original SAET-40 40mm Torpedo replaced by MK32 324mm Triple tube Torpedo, look closely at the pic

Well, Baltic sea isn't calm as you assume, and south china sea is not rough again as you presume . The primary reason could be that, these ships are designed for cold climates and rough winter conditions, may even lack proper A/C for cooling or storing foods. And mainly these are not open-sea ocean going (blue water navy) vessels. And they would out perform KCRs in too many ways despite of their age, in Patrol or ASW Patrol role. The only shortcoming is they are not equipped with anti-ship weapons or a decent cannon to counter surface threats.
The sole reason they are over-looked by Indonesians is the fact they were bought pretty cheap and from East Germany, i bet if those were from West Germany or British, or Dutch, these ships would have been praised :)

Yep, some ships were fitted with newer weapons for the fact that those systems were either not maintained by the supplier or gone out of the production ( like the torpedoes).

Air conditioning is not a problem though, TNI AL is known to install commercial air cons onboard it's ships, no problem.
Mainly I think because TNI AL is a NATO oriented Navy, from what I saw the Parchims are used as a workhorse patrolling the waters as if they are the Coast guard cutters, in military exercise it's mainly to bombard enemy Submarines using its RBU 6000 once an enemy submarine is located by sonar from other ships.

I wish Indonesia. Pakistan, Qatar and Turkey (and whoever else wants to join along) would design and build a new type of joint multipurpose frigate together. With each country contributing a share of the design costs, building specific segments and ordering any foreign parts in bulk, we could take advantage of economies of scale and bring the unit cost down dramatically. And in the end have a capable blue water frigate with a high level of modularity and joint operability.
