South Korea is prepared to deliver a second batch of Cheong Sangeo (K745/Blue Shark) torpedoes to the Philippine Navy (PN). However, Janes understands that the Philippines has delayed the procurement.
The deal was first announced in August 2021. At the time, the Philippines Department of National Defense (DND) said that the deal was reported to cost around PHP722.3 million (USD12.9 million).
A source with knowledge of the process told Janes that the documentation for the second sale batch was prepared in December 2022. “However, six months on, there has not been movement on the procurement,” the source added.
The source was speaking at the Langkawi International Maritime and Aerospace (LIMA) Exhibition 2023 held in Malaysia from 23 to 27 May.
Janes understands that the second batch of torpedoes is to equip the Leonardo AW159 helicopters in service with the PN and on the PN's two South Korean-made

The Excalibur Army MR-2 Viktor light air-defence vehicle displayed at the International Defence and Security Technology Fair (IDET) 2023 held in Brno, Czech Republic, from 24 to 26 May is being supplied to Ukraine.
An Excalibur Army representative told Janes on 24 May that two batches totalling 10 to 20 vehicles had been delivered during the fourth quarter of 2022 and that 130 to 140 were planned.
Some of the vehicles have been paid for by Czech citizens, he added. EUR3.8 million (USD4.1 million) of the nearly EUR4.3 million collected from 24,270 donors have paid for 15 Viktor vehicles for Ukraine, according to the Gifts for Putin website. In addition, the Netherlands is financing 100 vehicles, according to its Ministry of Defence's website.
The vehicle, which uses a Toyota Hilux chassis, is armed with ZPU-2 twin KPVT 14.5 mm machine guns that can be used against unmanned aerial systems, the Excalibur Army representative said.
The 14.5 mm ZPU series of anti-aircraft machine guns has an effective slant range of 1,402 m, according to

The US Army is testing two of its new air-defence sensors at White Sands Missile Range (WSMR) in New Mexico, the service recently announced.
The Lower Tier Air and Missile Defense Sensor (LTAMDS) has begun contractor verification testing (CVT), the army's Program Executive Office Missiles and Space (PEO MS) announced on 18 May. The army envisions the radar as a key technology for air defence in Guam and as a replacement for the Phased Array Tracking Radar to Intercept on Target (Patriot), service officials said.
Raytheon Missiles and Defense won a USD383 million contract in 2019 to build six prototypes for the service. Joe DeAntona, Raytheon Missiles and Defense's vice-president of business development, told Janes in March 2023 that the service had begun some testing of the sensors.

The Iranian military unveiled what was presented as a new, more accurate variant of the Khorramshahr, its most powerful ballistic missile, on 25 May.
Called the Khorramshahr-4 (Kheibar), the missile was displayed at an event attended by Defence Minister Amir Mohammad Reza Ashtiani and shown being launched from the missile testing facility in Semnan Province in a video and images.
The Iranian media reported that the new variant has a more advanced engine that uses hypergolic fuel, giving it a range of 2,000 km with a 1,500 kg warhead. Unlike other types of fuel/oxidiser combinations, the new propellant can be kept in tanks for years, shortening the preparation time for a launch to 12 minutes, making it a tactical weapon, it was claimed.
The new propellant also requires smaller tanks, reducing the Khorramshahr's motor section to about 13 m with the warhead adding about 4 m to the missile's length, it was reported. The airframe is also made of a stronger composite material.
