美国防部网站3月9日讯

在美国国防工业协会8日举行的太平洋作战科技研讨视频会议上，围绕量子科学、5G和定向能专题，国防部隶属研究与工程副部长办公室的一些技术官员发表了看法。在定向能方面，首席主任詹姆斯·特雷布斯称，经过多年的发展，国防部在定向能方面取得许多进展，但也开始暴露了一些问题。固体电子激光很有发展前景，工业部门正在自筹资金发展，进展较为顺利，能力不断扩展。国防部重点支持强激光发展，计划分“三步走”。第一步，目前有四家公司正在研发30万瓦激光系统，最早一年半开始交付，最晚两年交付。特雷布斯称，这些激光系统将交付军兵种进行试验与鉴定演示，旨在形成真正的实战能力。第二步，当上述激光系统转入生产阶段后，国防部将启动50万瓦激光器的开发工作，周期约两年至三年时间。第三步，完成上述工作后，国防部将立刻启动兆瓦级激光的研制工作。

DOD Officials Discuss Quantum Science, 5G and Directed Energy

MARCH 9, 2021 | BY DAVID VERGUN, DOD NEWS

Three of the Defense Department’s 11 principal directors of modernization within the Office of Defense Research and Engineering, discussed directed energy.

James Trebes, principal director for directed energy, said there’s been a lot of good development in directed energy after a number of years when there were some false starts.

“The technology provided by solid-state electric lasers, in particular, is really opening up a lot of opportunities. The industry is developing nicely. They’re expanding their capability and investing their own money. We’re funding a major effort in industry to build high-power lasers, Trebes said.

There’s a multiphase approach now underway with four companies under contract to make 300-kilowatt lasers, he said. The first will start arriving in 18 months and the last in about 24 months from now.

Those laser systems will be transitioned to the services for test and evaluation demonstrations, Trebes said. “These are not laboratory lasers. These are transportable lasers intended to demonstrate real military capability.”

He added: “These are not systems operated by PhD scientists in the lab. They’re out there being run by enlisted personnel in the real world across different combatant commands. We’re finding out what  does work. How do you integrate these things? How do you maintain them? What doesn’t work? This is where we learn what we really have to do. That’s a critical part of what we do.”

As soon as those lasers are produced, the department will begin developing 500-kilowatt lasers, [which] will take 24 to 36 months. Then the department will immediately start developing megawatt lasers, he said.

“There’s a clear, well-defined path to get to a very substantial laser capability,” he said. “There’s a smaller effort in microwave [technology] area going on.”

Some other focus areas include missile defense, he said.  “We are closely tracking our adversaries’ missile capabilities: cruise missiles, hypersonic missiles, ballistic missiles, and we’re looking at near-term counter missile capability. We’re also looking at offensive strikes again.”
