DroneShield has expanded its range of C-UAS products with the SonarOne system, its first underwater detection device. (DroneShield)
DroneShield's new SonarOne underwater threat detection system is designed to provide an easily operated sonar product that can detect multiple targets simultaneously, with the developer responding to growing naval demands for counter-unmanned underwater vehicle (C-UUV) and diver detection technology, the company told Janes.
SonarOne was announced in early September and is part of the company's DroneSentry autonomous fixed suite of sensors and countermeasures, which also incorporates radar and company technology like DroneOpt cameras and RfOne RF detectors. The sonar and other DroneSentry sensors can also be used with the company's DroneOptIde AI-driven computer vision technology.
SonarOne can be deployed underwater as part of a DroneSentry suite at a port or a harbour as a node within a multisensory suite. It can also be used as a standalone system and can be deployed from ships as well as fixed sites.
The new product is the first sonar device developed by DroneShield, which has until now largely focused on threats like unmanned aerial vehicles (UAVs) and electronic warfare (EW).

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
