诺思罗普•格鲁曼公司完成了美军下一代跟踪高超声速导弹卫星系统初步设计评审

      美国space daily网站2020年6月25日报道,作为美军发现跟踪中俄高超声速导弹下一代天基卫星系统的承包商之一,诺思罗普•格鲁曼公司和波尔航空航天公司成功地完成了承研分系统的初步设计评审。据公司项目主管称,这是具有里程碑意义的成果,对实现按期发射至关重要。及时发现、捕获、跟踪高超声速导弹和弹道导弹目标,对实现导弹防御是先决条件。美军已建成陆海空天多层探测体系,但难以发现高超声速导弹,为此,美军开始研制“下一代过顶持续红外系统”(NGPI),由国防部航天发展局、导弹防御局和国防高级研究计划局联合组织。系统首批3颗地球同步轨道卫星由洛克希德•马丁公司承制,2颗极地轨道卫星由诺思罗普•格鲁曼公司总包。按计划,2021年5月完成关键技术评审,2025年实现首发。
Northrop Grumman completes PDR for Overhead Persistent Infrared Subsystem

Northrop Grumman Corporation and Ball Aerospace have successfully completed the preliminary design review (PDR) for the Next-Generation Overhead Persistent Infrared (Next Gen OPIR) Geosynchronous (GEO) Block 0 mission payload.

Next-Gen OPIR is a satellite system that will provide improved missile warning capabilities that are more resilient against emerging threats. As the successor to the Space Based Infrared System (SBIRS), Next-Gen OPIR’s first block of satellites will include five space vehicles, three in geosynchronous earth orbit and two in polar orbit.

“The successful PDR for the Next-Gen OPIR subsystem is a significant program milestone,” said Bob Mehltretter, vice president, military and civil space, Northrop Grumman. “The subsystem and payload designs meet key mission performance requirements and support the national security imperative of launching the initial Next-Gen GEO mission payload.”

With the successful completion of the PDR, Northrop Grumman will continue maturing the designs of Next-Gen OPIR’s subsystem and its payload as it works to support the Air Force’s commitment to field new capabilities rapidly to meet evolving threats.

Northrop Grumman and Ball Aerospace are on track to complete the payload’s Critical Design Review in May 2021.
