Indonesian state-owned shipbuilder PT PAL has unveiled a locally designed autonomous submarine concept at the Indo Defence 2022 exhibition.
Speaking to Janes at the exhibition, PT PAL described the concept as a testament of the shipbuilder's latest capabilities and said it has been conceived with support from the Indonesian Ministry of Defense (MoD).
The concept is known as the Kapal Selam Autonomous (KSOT) and it has an overall length of approximately 25 m, a diameter of about 4 m, and a submerged displacement of about 262 tonne. According to PT PAL's CEO Kaharuddin Djenod, PT PAL has designed the KSOT such that it can be assembled at its facilities in Surabaya within 12 months.
It will be able to take on light combat operations with decisions aided by onboard artificial intelligence systems, he said, adding that the KSOT is more than just an “underwater drone” as it will be equipped with lethal effectors in addition to sensors and monitoring equipment.

Italian shipbuilder Fincantieri announced on 28 March that it has signed a EUR1.18 billion (USD1.27) contract for two multirole offshore patrol ships (Pattugliatore Polivalente d'Altura: PPA) with the Indonesian Ministry of Defense (MoD).
However, Indonesia's ability to fund this commitment is presently unclear given the lack of an allocation for this programme in the country's defence budget.
The PPA is a class of 143 m warships that can be configured for a wide spectrum of missions ranging from ‘light' low-tempo maritime surveillance operations to ‘full combat' higher-end warfighting scenarios. Depending on the configuration, the vessels displace between 5,800 and 6,300 tonnes.
Italy has commissioned three of the vessels and the ships were inducted between March 2022 and September 2023. The Italian Navy is expected to receive its fourth and fifth PPAs in 2024.

The accuracy of the estimated procurement cost of the proposed US Coast Guard (USCG) Polar Security Cutter (PSC), given its size and internal complexity, is a potential issue of concern, according to the US Congressional Research Service (CRS).
“The PSC's estimated procurement cost per weight is roughly half that of the [US] Navy's LPD-17 Flight II and LHA amphibious ships,” the CRS said in its report, Coast Guard Polar Security Cutter (Polar Icebreaker) Program: Background and Issues for Congress , released on 25 March.
“These amphibious ships are equipped with expensive combat system equipment that is not included in the PSC design, but whether this would account for all of the difference in cost per weight between the PSC design and the two amphibious ship designs is not clear,” the CRS said. “If substantial cost growth occurs in the PSC program, it could raise a question regarding whether to grant some form of contract relief to the PSC shipbuilder.”

The Republic of China Navy (RoCN) has received its fifth and sixth Tuo Chiang-class guided-missile corvettes.
Presiding over the vessels' handover ceremony on 26 March at Yilan was Taiwanese President Tsai Ing-wen who in an official social media post on the same day described the handover event as “an important step forward for Taiwan's indigenous naval defence”.
The Tuo Chiang class is a catamaran-hulled corvette that features a wave-piercing form factor with reduced radar cross-section (RCS) exteriors. It was developed by the country's National Chung-Shan Institute of Science & Technology (NCSIST) with local shipbuilder Lung Teh.
First-of-class ROCS Tuo Chiang (618) was commissioned in December 2014. The programme's second-of-class onwards are based on an improved design with a longer overall length of 65 m and a higher displacement of 685 tonnes. The first-of-class displaces about 600 tonnes and has an overall length of about 60 m.
The vessels that were handed over on 26 March are named An Chiang (625) and Wan Chiang
