레이저 한화 에어로스페이스, 대드론 레이저 무기 양산계약 체결

[위종민]

방사청이 한화 에어로스페이스와 고출력 지향성 에너지 무기 양산 계약을 체결했네요. 올해 후반기 배치 예정이라고 합니다. 

블록1은 20kW 출력으로 2019년부터 개발했었다고 합니다. 고정식 운용으로 추정되고 사거리는 3km라고 하네요. 발당 사격비용은1천원~2천원, 미화 1.5달러라고 하고, 표적 비활성화에 필요한 조사시간은 최대 10초! 라고 ㄷㄷㄷ 

함정용의 블록3는 100kW, 블록2는 30kW라고 하네요. 

고정식이니 장비 냉각이나 전자장비 통합 등의 문제는 적겠습니다만, 50kW 출력으로도 사막 등 환경에선 에너지 집중이 어려웠는데 20kW 출력이 충분할 지 모르겠습니다. (  https://cafe.daum.net/NTDS/5q1/902 )

Republic of Korea to Field Counter-drone Laser

The Republic of Korea’s Defense Acquisition Program Administration (DAPA) announced it has awarded Hanwha Aerospace a contract for the mass production of a high-powered directed-energy weapon.

The Laser Anti-Air Weapon Block 1 has been in active development since 2019 in a US$63 million program. Following a series of live-firing tests in April 2023 where the demonstrated a 100% success it was determined to be ready for production. An initial fielding is scheduled for later in 2024.

According to DAPA background the Block 1 uses an optical fibre laser developed by the Agency for Defense Development and Hanwha. The system has a power of 20kW which has proved sufficient for engaging and downing small drones and unmanned aerial vehicles including fixed wing and quad-copters. The weapon system is housed in an ISO rigid shelter that can be carried on a truck or air-transported. The package appears to have a 360 degree laser, a panoramic optical sight, and integrated generator power. Study of the model displayed by Hanwha suggests the laser itself can be retracted into the shelter itself likely for transport and weather protection when not in operational ready state. The configuration suggests the Block 1 is intended for stationary employment. This coupled with an effective three kilometer range the system is likely most appropriately employed defending high value fixed site assets against drone attack.

The benefits of a laser in this air defense role particularly are its accuracy, unlimited “magazine”, and projected low cost per kill over other more traditional weapons. Since the laser travels “strait at the speed of light” aiming is relatively straight forward. In addition, as long as it has power it is able engage targets. Further, the case can be made that its is more cost effective particularly over guided missile solutions which are commonly tens of thousands of dollars. The 20kW Hanwha Block claims a cost about 1,000 to 2,000 won or US$1.50 per shot. Disadvantages include its difficultly engaging in smoke, fog, rain and the overall size required of laser systems due to the power and cooling demands. A further issue can be the potentially long interception time – essentially meaning the length of time that the laser beam must dwell on the target to assure it is disabled. This can be as great as ten seconds.

DAPA is pursing other more powerful laser weapons to address some of these issues and to expand the targets against which they can be employed. Its Laser anti-aircraft Weapon Block-3 being developed is to have an output of 100kW for shipboard use. This is considered by many experts as having the most practical tactical value and target versatility. This Block-3 is projected to be ready by mid-2030. A 30kW laser (Block 2) may also be pursued which could be available earlier though more likely being an upgrade to the Block 1. Although the US Navy successfully fired a laser against a missile target in 2022 and the United Kingdom demonstrated its Dragon Fire 30kW laser in early 2024, the RoK appears to be the first to move forward with a production system.

표적을 찾아 조준하는 수단은 뭐죵? 레이다? EO/IR?

표적을 찾는 붐에 달린 저 물건은 레이더같은데, 조준용 센서는 생긴 것만 보면 EO/IR 센서같습니다.

최소한, 건조한 겨울 외에는 무용지물 소릴 듣겠네요.

저출력이라도 복수의 포대가 단일목표를 동시공격하면 효과가 있다고 판단하나 봅니다.
출력 높이는게 용이할지, 포대 통제하는 것이 더 용이할지에 따라 선견지명이 될지 헛수고가 될지 결정될것 같네요

각속도가 얼마인 표적까지 계속 물고 있을 수 있을지도 관건일 것 같습니다. FPV 드론들은 운영자의 능력에 따라 기동도 예측불허일 텐데, 그런 물건들을 10초 동안 계속 비춰줘야 한다면..
