The South Korean shipbuilder Hanwha Ocean which is proposing two different submarine types for a Philippine Navy submarine requirement for two conventional diesel-electric submarines, is also offering a procurement solution which involves training of personnel, setting up support infrastructure, creating base infrastructure and also providing financing for the deal.
The Philippines is looking to procure atleast two conventional submarines under its 'Re-Horizon 3' military modernisation programme as it currently does not operate submarines. Hanwha Ocean is proposing its KSS-III PN submarine and the Ocean 1400PN submarine. Both submarines are being offered with torpedoes, missiles and mines from LIG Nex 1
Speaking to FW MAG, a Hanwha Ocean official said the Korean shipbuilder was offering a total solution package, which would involve a comprehensive training and education programme to train Philippine Navy personnel, MRO services, creation of base infrastructure, and purchase financing.
The Republic of Korea has offered to provide 100 percent financing for the purchase of the KSS-III PN submarine, while for the Ocean 1400PN submarine, the financing will also extend to purchase of weapons.
The KSS-III PN submarine, is based on Hanwha Ocean’s KSS-III Batch-II submarines. However, the advanced conventional diesel-electric submarines for the Philippines will not receive an Air Independent Propulsion (AIP) system and the Vertical Launch System (VLS), to reduce operational and sustainment costs.
“The KSS-III PN is a customised version of the KSS-III and is specifically designed for the operational environment of the Philippines. The removal of the AIP and the VLS, results in a more compact design, optimized for underwater operations with advanced noise reduction to enhance stealth,” the official added.
The KSS-III PN submarine makes use of a Li-ion battery pack, which as compared to a Lead Acid battery pack, can be charged 4,000 times, and once fully charged allows the submarine to remain underwater for six days at a stretch. It takes seven hours to fully recharge the Li-ion battery on the surface. The submarine can stay at sea for 50 days at a stretch covering 14,000 nautical miles. It can carry a total of 20 weapons, which can be launched from any of the six launch tubes. The weapon fit comprises of Submarine Launched Cruise Missiles (SLCM), Anti-Ship Missiles (AShM), torpedoes and mines. The KSS-III is a proven submarine with three of them in active service with the Republic of Korea Navy (ROKN). Three more, currently under construction at Hanwha Ocean and are slated for delivery in 2027, 2028, 2031.
The other submarine being offered for the Philippine Navy requirement by Hanwha Ocean is its Ocean 1400 PN submarine (erstwhile DSME 1400) and is based on the Germany’s Type 209/1200 submarine and has also been exported to Indonesia as the Nagapasa Class submarine. The Hanwha Ocean 1400 PN is based on the submarines sold to the Indonesian Navy (Tentara Nasional Indonesia – Angkatan Laut: TNI-AL), all three of which were delivered by 2021. The 1400 PN has a displacement of 1400 tonne and features conventional lead-acid batteries but is fitted with a state-of-the-art CMS, sonar, radar and sensors. It can carry a total of 14 torpedoes and mines.
