The Japan Air Self-Defense Force (JASDF) scrambled its fighter aircraft 235 times in the first quarter of 2022. This represents a 65% increase over scrambles in a similar period in 2021.
Data released by the Japanese Ministry of Defense (MoD) on 6 July shows that 142 scrambles were conducted in the first quarter of 2021. The Japan MoD data also shows that the 2022 first quarterly scramble figure has exceeded 200 for the first time since 2019.
“The number of scrambles in the first quarter of 2022 is relatively high. It can be said that it is at a high standard,” the Japan MoD said in a statement.
The MoD attributed the increased number of scrambles to sustained activities by Chinese aircraft.
The data specifies that JASDF aircraft conducted 171 scrambles in response to Chinese military aircraft during the first quarter of 2022. Fifty-eight scrambles were conducted in response to military aircraft from the Russian Federation.

China's development of military air platforms continues to show strong links to designs and concepts originating from the West.
During Airshow China 2022, 121 aircraft (including models) and 54 types of ground equipment were displayed by more than 740 companies worldwide, according to Chinese state-owned media. Out of this, 55% of exhibits were unveiled for the first time, according to the Aviation Industry Corporation of China (AVIC). The corporation added that 43 exhibits were domestically developed unmanned aerial vehicles (UAVs).
In addition, about 50 aircraft and associated weapons and equipment displayed at the air show were developed by domestic industry and operated by the People's Liberation Army Air Force (PLAAF), AVIC said.
Janes assessment of 14 technology demonstrators, in-service aircraft or models exhibited at the air show found design or capability similarities with platforms in other countries.

The Royal Australian Navy (RAN) is acquiring five Bluebottle unmanned surface vessels (USVs) to enhance its ability to experiment and advance the operational employment of uncrewed systems under, on, and above the water.
Disclosing a AUD4.9 million (USD3.3 million) contract with Sydney-based Ocius Technologies, Rear Admiral Peter Quinn, head of the Navy Capability in the RAN, said on 25 November that this represented a significant investment in sovereign industry capability to advance the ability of the RAN to effectively employ robotic and autonomous systems.
“We have vast areas that we need to patrol, which we can't do with a small number of crewed ships. We have to and will be investing in uncrewed platforms that will be out there persistently conducting surveillance,'' he said.
The 22 ft solar, wind, and wave-powered vessels would be used in developing new uncrewed underwater systems technology, and as testbeds for above-water and low-water surveillance, he said.
China's J-15 naval jet appears with indigenous WS-10 engines

A Shenyang Aircraft Corporation (SAC) J-15 ‘Flying Shark' naval fighter has been fitted with what appears to be a pair of domestically developed engines.
The aircraft was spotted in a video imagery of a hangar at an SAC factory. The footage was aired on 23 November during a China Central Television (CCTV) news report on the 10th anniversary of the J-15 starting sea trials on China's first aircraft carrier, the Liaoning.
Janes assesses that the new engine is a variant of the Liming WS-10 Taihang engine. There is a roughly even chance that the ‘B' variant of the Taihang has been installed in the jet. According to Janes Aero-Engines data, the WS-10B is potentially a more powerful version of the WS-10A. The thrust rating of the WS-10B is 135 kN (30,350 lb st).
