The
Bung Tomo
class
is a class of three Indonesian multi-role patrol
corvettes
or 'multi-role light frigate' (MRLF) by
Indonesia
.
[5]
[6]
They were originally built for the
Royal Brunei Navy
(RBN;
Malay
:
Tentera Laut Diraja Brunei
, TLDB), and named
Nakhoda Ragam
-class corvettes
, but were ultimately bought by Indonesia and subsequently renamed.
[7]
The class is named after
Bung Tomo
, a noted leader of Indonesia's independence movement.
Background
[
edit
]
The
Nakhoda Ragam
-class ships in
Barrow-in-Furness
, 2007.
The three vessels were built by
BAE Systems Marine
(now
BAE Systems Maritime - Naval Ships
). The contract was awarded to
GEC-Marconi
in 1995, and the ships, a variant of the F2000 design, were launched in January 2001, June 2001, and June 2002, at the then BAE Systems Marine yard at
Scotstoun
,
Glasgow
. The customer (Royal Brunei Navy) refused to accept the vessels, due to claims by the Royal Brunei Navy that the ships fail to meet the required specifications;
[8]
though opinion in the shipyard was that they were too complex for a small navy to operate.
[9]
The contract dispute became the subject of
arbitration
.
[10]
When the dispute was settled in favour of BAE Systems, the vessels were handed over to
Royal Brunei Technical Services
(RBTS) in June 2007.
[9]
In 2007, Brunei contracted the German
Lurssen
shipyard to find a new customer for the three ships. In 2013, Indonesia bought the vessels for
£
380 million, or half of the original unit cost.
[11]
The ships are now in service with the
Indonesian Navy
.
The ships were originally armed with
MBDA Exocet
Block II anti-ship missiles and
MBDA Seawolf
air defence missiles. The main gun is an Oto Melara 76 mm. The ship also carries two
torpedo tubes
, two 30 mm remote weapon stations, and has a landing pad for a helicopter. As 2018, the MBDA Seawolf missile was out of service due to expired, and there was plan to replace it with
VL Mica
[12]
Operational history
[
edit
]
In late December 2014, KRI
Bung Tomo
was involved in search and recovery operations of the
Indonesia AirAsia Flight 8501
which crashed off the
Java Sea
between the islands of
Belitung
and
Borneo
.
[13]
Later in early January 2015, KRI
Usman Harun
was deployed to search for the
black boxes
as the ship is equipped with the Thales Underwater Systems TMS 4130C1 hull-mounted sonar.
[14]
[15]
In late April 2021, KRI
Bung Tomo
was involved in the search for the then missing
KRI
Nanggala
(402)
[16]
Ships of the class
[
edit
]
KRI
Bung Tomo
is named after
Sutomo
, the leader of Indonesian guerrillas during the
Battle of Surabaya
. The naming of KRI
John Lie
memorialises the first
Chinese Indonesian
to be honored as
National Hero of Indonesia
, who was also one of the first high ranking navy commanders during the
Indonesian National Revolution
. The naming of KRI
Usman Harun
memorialises
Harun Said
and
Osman Hj Mohd Ali
, who were executed by
Singapore
after the
MacDonald House bombing
, creating a controversy between the two nations.
[17]
Modernisation
[
edit
]
On 10 March 2020 in Jakarta,
Len Industri
and Thales signed a contract for the complete modernisation of the Indonesian Navy KRI
Usman Harun
multi-role light frigate's mission system, witnessed by King
Willem-Alexander of the Netherlands
and
Indonesian Minister of Trade
Agus Suparmanto
. This upgrade for the KRI
Usman Harun
is expected to be completed by the end of 2023, and it will considerably extend the service life of the frigate.
[22]
A final specification was drawn up, including Thales's TACTICOS Combat Management System,
SMART-S Mk2 3D
, and
STIR 1.2 EO Mk2 radars
, a Vigile Mk2 ESM, and two new tactical data links ? Link Y Mk2 and a tactical data link that will be delivered by PT Len Industri, providing connectivity to Indonesia's military communications network and enabling the corvette to play its full part in wider naval task forces. The systems' commonality with those on other Indonesian ships would reduce training time and facilitate management and maintenance. Existing weaponry will also be fully integrated, and a new
VL MICA
surface-to-air missile system added; a significant boost for the vessel's air defence capability.
