随着战场上小型无人机系统发动攻击的威胁日益增加，诺斯罗普·格鲁曼公司正在推出基于火炮的防空系统，旨在击落空中威胁的浪潮。
With the growing threat of attacks by small unmanned aircraft systems on the battlefield, Northrop Grumman is pitching gun-based air defense systems designed to take down waves of aerial threats.
在美国陆军协会的年度大会上，诺斯罗普展示了其最新的50毫米基于火炮的防空系统，该系统被称为“突袭猎手”，以及M230的最新迭代版本。
At the Association of the United States Army’s annual convention, Northrop showed off its newest 50mm Gun-Based Air Defense system dubbed the Raid Hunter and the latest iteration of the M230.
这两个系统均属于诺斯罗普专利的“布什马斯特链式机枪”系列，该系列是一种中口径、车载机枪，通过外部电源运行。
Both systems are part of Northrop’s patented Bushmaster Chain Guns, a collection of medium-caliber, vehicle-mounted machine guns that operate using an external power source.
公司指挥与控制及武器集成副总裁兼总经理肯·托多罗夫称，“突袭猎手”是一种“具有成本效益、灵活的工具，旨在决定性地击败不断演变的威胁”，这些威胁旨在压倒防御系统。
Kenn Todorov, the company’s vice president and general manager of command and control & weapons integration, called the Raid Hunter “a cost-effective, flexible tool to decisively defeat evolving threats” intended to overwhelm defense systems.
根据规格表，该系统依赖于AI目标定位和精确制导的50毫米弹药，这些弹药采用近炸引信，在目标附近引爆。
According to the specs sheet, the system relies on AI targeting and precision-guided 50mm ammo, which proximity fuzes detonate near a target.
托多罗夫补充说，该武器“通过提供快速、高容量的防护，针对巡航导弹和无人机群等复杂的大规模空中威胁，弥补了关键的短程防御缺口。”自8月推出以来，“突袭猎手”已完成空气动力学测试——即针对空中目标进行测试——该测试证实了测试前的预测和性能预期。
Todorov added that the weapon “addresses a critical short-range defense gap by delivering rapid, high-capacity protection against complex, mass aerial threats like cruise missiles and drone swarms.”Since its introduction in August, the Raid Hunter has completed aeroballistic testing — meaning it was tested against aerial targets — that confirmed pre-test predictions and performance expectations.
该系统以阿帕奇攻击直升机上的M230机枪为原型，M230链式供给双供给布什马斯特链式机枪（即M230LF）可安装于多种车辆，从四轮驱动车辆到大型地面车辆再到巡逻艇。
Modeled after the M230 gun for Apache attack helicopters, the M230 Link Fed Dual Feed Bushmaster Chain Gun, or M230LF, can be mounted to an assortment of vehicles, ranging from 4x4s to large ground vehicles to patrol boats.
但其特别之处在于，它可以使用两条供给路径，使操作员能够在标准近炸引信30x113毫米弹药（用于对抗无人机）和高爆双用途弹药（用于装甲目标）之间切换。
But what’s special about it is that it can use two feed paths, which allow operators to switch between standard proximity-fuzed 30x113mm rounds for countering drones and high-explosive, dual-purpose rounds for armored targets.
采用双供弹系统后，操作员能够快速选择最适合目标的弹药，而无需完全更换弹药。此外，新型变体与单供弹型号共享60%的零部件。
With a dual-feed system, an operator will be able to quickly select the best ammunition for the given target rather than completely changing out the loads. Plus, the new variant shares 60% of the same parts as the single-feed model.
根据诺斯罗普的规格表，M230LF每分钟可发射200发弹药，平均故障间隔为22,000发，且“高度可靠”。
According to Northrop’s spec sheet, the M230LF can fire 200 rounds per minute with a “highly reliable” 22,000 rounds between mean time of failure.
