Japan releases audio recordings in radar lock-on dispute with South Korea

After first releasing video footage of an incident in which a South Korean destroyer allegedly trained its fire-control radar on a Japanese patrol plane in December 2018, Japan’s defense ministry has now released an audio file with the aim of proving its allegations.

In a statement on January 21, the defense ministry said it was releasing data of the radar waves converted to sound as further evidence of the irradiation of the fire-control radar.

“The Ministry of Defense (MOD) has made endeavors in the past for close communication to take place between the defense authorities of Japan and the Republic of Korea (ROK), and in this spirit, regarding the current issue concerning the fire-control radar irradiation by an ROK destroyer, a series of consultations have been held between Japan and the ROK. However, it is extremely regrettable that even today, the difference between the respective understandings regarding major issues, including whether or not there was an irradiation of fire-control radar, is not yet resolved,” the ministry said.

“We hope that this announcement will lead to the prevention of similar incidents in the future, and we will continue to make sincere efforts toward continuous Japan-ROK and Japan-ROK-US defense cooperation.”

The dispute between the two countries started on December 20 when a Maritime Self Defence Force P-1 patrol aircraft, flying within Japan’s exclusive economic zone (EEZ) in the Sea of Japan, was irradiated by a fire-control radar from the ROK destroyer.

South Korea said the destroyer did not direct its radar at the JMSDF plane adding that the vessel was in the process of rendering assistance to a North Korean ship drifting at sea.

Responding to South Korean claims, Japan said that a fire-control radar is designed to be used to measure the precise orientation of and distance to an attack target, and that it is not suitable for searching over a wide range. A surface search radar is more appropriate for the purpose of searching for missing ships, the ministry added.

“Upon careful and meticulous analysis by the MOD’s specialized unit of the frequency, intensity, waveform, etc. of the radar waves directed at the MSDF P-1, the MOD has confirmed that the P-1 was continuously irradiated for a certain period, multiple times by the fire-control radar (STIR-180) of the ROK destroyer that was being photographed. The STIR-180 was not mounted on the patrol and rescue vessel that was nearby at the time, and the fact the ROK destroyer directed its radar is clear from the

.”

In the same statement, the defense ministry said it was terminating talks with its South Korean counterpart related to the dispute.

Responding to Tokyo’s move, a South Korean defense ministry spokesperson said the audio released by Japan was just mechanical sounds from which the detection date, angle and traits of electromagnetic waves could not be verified. The spokesperson also expressed regret over Japan’s decision to stop consultations aimed at verifying the facts.

The sale, worth an estimated $2.15 billion, would bolster Japan’s existing sea-based Aegis capabilities. The island nation is in the process of increasing its missile defense capabilities, both through additional Aegis buys and through the co-development of the

Although not specified in the DSCA announcement, a government official confirmed these two systems are for Japan’s planned

, which are expected to be operational by 2023.

Included in the potential package: two Aegis weapon systems, two multimission signal processors, and two command-and-control processor refreshes, alongside radio navigation equipment, ordnance, identification friend or foe systems, and construction services for six vertical launch system launcher module enclosures.

Tuesday’s announcement is the first DSCA notification to be posted since Dec. 18, just days before the longest government shutdown in U.S. history began.

Speaking to reporters last week, Andrea Thompson, the U.S. State Department official who oversees the FMS process, said the shutdown was slowing down the process of clearing sales requests from foreign customers — notable, as the Trump administration has made

a key part of both its foreign policy and economic growth strategy.

“There will be a bit of a bump — a gap, if you will — just because we haven’t had the engagement with [Capitol] Hill” normally seen in the process, Thompson said then. “We’ll be able to make up some ground, but I am a realist. We have to work harder if we are going to have the numbers we had last year.”

Japan has recently spent heavily on American defense items. In September, the nation was cleared to spend $3.14 billion on nine

, and in October it agreed to pay more than half a billion dollars for SM-3 missiles.

In the recently released

, the U.S. Department of Defense identified that working with partners in the Pacific — notably Japan and South Korea — is the “cornerstone” of American security in the region.

“Japan is one of our strongest missile defense partners, and works together with the United States to strengthen cooperative missile defenses against regional missile threats,” the review

. “Going forward, DoD will work with allies and partners to prioritize these types of missile defense integration opportunities that contribute to more effective protection of the United States, its allies and deployed forces.”

DSCA announcements do not mean sales are final. The announcement serves as notification to Congress about the potential sale, which can be vetoed by the Senate; once cleared, negotiations between the customer and contractor can lead to changed quantities or dollar figures from the original announcement.

Hyuga Class DDH or still a potential escort CVH at times?


One thing is for sure, the Izumo and Kaga are both going to get ski-jumps and be enabled to carry up to 24 F-35Bs. And there is still a persistant rumor about another larger class of either 2 or 4 carriers depnding on how the PLAN responds to the Izumo class as fixed wing carriers.

Japan commissions second Asahi-class destroyer JS Shiranui
Please, Log in or Register to view URLs content!

Japan’s second Asahi-class destroyer, the JS Shiranui, entered Japan Maritime Self Defense Force (JMSDF) service in a ceremony at Mitsubishi Heavy Industries’ Nagasaki Shipyard on February 27.

The lead ship in the class was commissioned a year before, on March 8, 2018.

The 5,100-ton general-purpose escort destroyers were previously designated as 25DD and are designed on the basis of Akizuki-class destroyers but with a focus on anti-submarine instead of anti-air warfare.

JS Shiranui (DD-120) was launched in October 2017 and was commissioned without delays.

Asahi-class destroyers are lauded as fuel-efficient ships featuring COGLAG, a combined gas turbine engine and electric propulsion system. They measure 151 meters in length and reach speeds of 30 knots, according to the Japan defense ministry. Armament includes Mark 41 vertical launch systems for self protection, 62-caliber naval guns, close-in weapon systems and two Mark 32 surface vessel torpedo tubes.

The destroyers will have a complement of around 230 and embark one Mitsubishi-built SH-60J/K are anti-submarine patrol helicopter.

Asahi-class destroyers are the first JMSDF ships to deploy with periscope detection radars in addition to being equipped with new towed array sonars.
good luck to her, too

this thread dead? but Japanese Attack Helicopter Program Lives

Mar 4, 2019
Please, Log in or Register to view URLs content!

The Japanese Ministry of Defense is likely to move ahead with an attack helicopter acquisition in 2019, even though the program was left out of a five-year procurement plan published in December, an industry source said.

The army sees the program as urgent in part because the oldest units among the Bell AH-1S Cobras that need to be replaced are running out of airframe life, the source said. In addition, the combat value of the AH-1Ss in the 2020s is doubtful, other industry sources have said.

The ministry is likely to issue a request for proposals this year for the program, the New Attack Helicopter (NAH), the first source said. Purchase of 30–50 helicopters is proposed.

The ministry and the army have two ways of funding the program in the absence of provision in the five-year plan, the Mid-Term Defense Plan, said the source, who has been following the program. One is to look for savings or unspent funds in other programs from year to year during the period of the plan, which begins on April 1, 2019; the Japanese defense forces have done this previously. The other is to propose an update of the overall plan around 2022.

Six companies are competing for the NAH order, with widely varying offerings.

Lightnings. If funds must be scrounged from other parts of the defense budget, the temptation to economically import should be stronger than usual—yet politicians and officials might make more money available if the helicopters will be made in Japan.

Domestic political support should also help the KHI and MHI offers, but other factors include the need to operate helicopters from ships, for which the Viper, alone among the candidates, is a dedicated design.

The army has 56 Cobras, survivors of 90 built in the 21 years beginning in 1979 by Fuji Heavy Industries, now called Subaru. The inventory has declined from 59 in the past few months.
