Radio Mods For Keris Class

SHAH ALAM: Radio mods for Keris class. Barely two years into their service, RMN is seeking to modify the V/UHF radios on the two Keris class LMS, KD Keris and KD Sundang. The notice for quotation for the modifications, were published on the ePerolehan website on August 24 and closes on August 29.

Although the title of the NFQ is – PEMBAIKAN RADIO V/UHF KD KERIS. RUJUK DSAT/SH/SENG/21/52/ PEMBAIKAN RADIO V/UHF KD SUNDANG. RUJUK DSAT/SH/SENG/21/51 –, the publicly available specifications for both sounds pretty much like they are replacing the whatever China-made type V/UHF radios on the ships. Note that the first item on the specification list says “replace”.

It will be odd to say the least if they have two sets of incompatible V/UHF radios on the ships.

Anyhow, I am aware that there is a report out there telling us that RMN has a detailed list of defects on board the LMS, which are mostly China-made stuff. AFAIK this is the first time that RMN is actually doing something about it. The modification/replacement work is expected to be done at the Kota Kinabalu naval base where the LMS squadron are based.

Sundang was in the peninsula recently as she took part in the recent Ex Taming Sari 20/21. RMN has not revealed whether Sundang took part in the gunnery exercise during the exercise. She also visited RMN base in Tanjung Pengelih on August 19 after the exercise as a courtesy visit.

  1. Basically TLDM wants the radio that was specified on the LMS, which is commercial grade ICOM sets, to be replaced with military spec radios.

    Nothing wrong with that.

  2. Perhaps TLDM found out their China made radios were leaking info to China military and wants to stop it. You know, like how USA are accusing certain Chinese phones of feeding user info back to China. They even banned Pentagon staffers from using any Chinese branded phones.

  3. Defective Chinese Components who would’ve thought? Might as well purchase and install extra weapon systems on LMS, ship to ship missiles or ASW capability would be nice . Its meant to be a corvette after all not an oversize patrol boat

  4. “…RMN has a detailed list of defects on board the LMS, which are mostly China-made stuff…”
    Defect as in “politely indicating these components are not competible” with RMN requirement? Rightfully a defect on these new ships would be under warranty and to replace them with a different component will only cost more. And the communication radio is only the beginning of the list?

  5. The LMS came with various Chinese made gear because it was practical and to suit the budget. The RMN had long factored in that in due course a number of components would have to be replaced. The primary reason behind replacing the Chinese radios has more to do with compatibility with other (Western) radios used on other assets.

    It has less to do with โ€˜military specโ€ or security. Many UHF/HF/VHF transceivers have stuff like frequency hopping and encryption but by and large intercepting stuff broadcast on open airwaves is relatively easy. Top security stuff will not be transmitted on radio.

  6. So we can assumed that the future 2 LMS also will get the new radio mods right? And any early news about LMS batch 2? If any..How about thales/aselsan LMM platform on future batch 2 of LMS? and possibly on Kedahs too..

  7. @Firdaus
    We can assume that if future LMS is from Western yard equipped with Western spec radios, it would not “breakdown” so soon and replaced.

  8. @joe..i mean our 2 future lms from china..for lms batch 2..can put thales hitrole 40mm and lmm cuz lmm is versatile platform can be configured as ssm or sam but their range is kinda limited for about 8km only..should be cheaper or the same price bracket as mistral missile.

  9. @Firdaus
    It depends on what role TLDM envisions the LMS class supposed to do, and inm AA boat isn’t part of it. Other than point defence, such short range has limited use. IMHO it should be a highly configurable platform for the more mundane tasks; peace time patrol, minesweeping, able to launch RHIB for interdiction, cadet training, SAR, able to mount AShM if necessary.

    Rather than 40mm gun, better just standardise to 30mm NATO either MSI DS30M or Aselsan SMASH.

  10. Firdaus,

    Three points.

    Firstly integrating non Chinese made stuff to the 4 LMSs will be problematic.
    Secondly, yes on paper various things can be added but bear in mind that what will ultimately make the difference is not so much the actual weaponry but how the ships are employed; alongside what assets and how networked they are.
    Thirdly, the RMN wants to spend the bare minimum on them; preferring to keep the cash for the follow on LMS batches which the RMN is determined to fully fit out.

    Yes the decision to order the LMSs from China was highly flawed but it was driven by political and financial reasoning and the RMN was desperate for new hills to replace current assets; in order to perform the peacetime/low threat role.

  11. Not only radio’s, but need to review combat management system. We need to secure our LMS ship from any signal interfence. Off course China would know system inside LMS ship. To deter electronics warfare from China, if let say any engagement at National Sea(SCS), we can encounter any signal that will interfere our ship system n movement.
