Leidos Holdings, Inc.

Leidos' largest segment. It builds and guards the computer systems and networks that US intelligence agencies and the military use every day, and it moves old government systems onto the cloud. Demand tracks government spending on cyber defense and modern IT. Long, multi-year contracts and required security clearances make it hard for a rival to take this work away.利多斯最大的部门。它为美国情报机构和军方建造并保护每天使用的计算机系统和网络，并把旧的政府系统迁移到云端。需求跟随政府在网络防御和现代化信息技术方面的支出而变化。多年期的长期合同和所需的安全许可，使竞争对手很难抢走这部分业务。

• Cybersecurity and secure networks网络安全与安全网络 — Leidos builds digital locks and alarms for government computers, so outside attackers cannot steal secret data.Leidos 为政府计算机打造数字锁和警报，让外部攻击者无法窃取机密数据。
• Cloud computing services云计算服务 — Leidos moves old government computer systems onto shared, internet-based systems (called "the cloud"), so agencies work faster and pay less to store data.Leidos 把老旧的政府计算机系统迁移到共享的、基于互联网的系统（称为“云”）上，让各机构工作更快、存储数据花费更少。

This segment runs computer systems for health agencies and everyday civilian government bodies. It manages patient and veteran health records, guides air traffic, and operates the scanners that check travelers and cargo at US borders. This work is steady and does not depend on defense budget cycles, so it gives Leidos a stable base of revenue.该部门为卫生机构和日常民用政府机构运行计算机系统。它管理病人和退伍军人的健康记录，引导空中交通，并运营检查旅客和货物的美国边境扫描设备。这部分业务稳定，不依赖国防预算周期，因此为利多斯提供了稳定的收入基础。

• Veteran and public health records退伍军人和公共卫生记录 — Leidos manages the systems that store patient health records for agencies that care for former soldiers, so doctors find a patient's history fast.Leidos 为照护退伍军人的机构管理存储病人健康记录的系统，让医生能快速找到病人的病史。
• Air traffic and border systems空中交通和边境系统 — Leidos runs the computer systems that guide airplanes for the US air-traffic agency, and builds scanners that check travelers and cargo at borders.Leidos 为美国空中交通机构运行引导飞机的计算机系统，并制造在边境检查旅客和货物的扫描仪。

This segment sells Leidos' security scanners and engineering skills to friendly foreign governments and some private companies, outside the core US federal market. It lets Leidos use technology it first built for the US government to reach new customers abroad. It is one of Leidos' smaller segments, so revenue here is less steady than the US government work.该部门把利多斯的安全扫描设备和工程技术，出售给友好的外国政府和一些私营公司，业务范围在美国联邦政府核心市场之外。这让利多斯把最初为美国政府开发的技术用于开拓海外新客户。这是利多斯较小的部门之一，因此这部分收入不如美国政府业务稳定。

• Security scanners for allies面向盟友的安检扫描仪 — Leidos sells airport and border scanners, which use X-rays to see inside bags and containers, to governments such as the UK and Australia.Leidos 把用X射线看清箱包和集装箱内部的机场和边境扫描仪，卖给英国、澳大利亚等国家的政府。
• Energy and engineering services能源和工程服务 — Leidos gives technical help to energy companies, using skills it first built for government work.Leidos 用最初为政府工作练就的技能，为能源公司提供技术帮助。

This segment builds physical defense hardware, not software or services. It makes sensors that track missile threats from space, and it builds and repairs spy planes and unmanned sea vehicles for the military. Because it delivers physical equipment, its revenue depends on production schedules and hardware orders rather than long-running service contracts.该部门建造实体防御装备，而不是软件或服务。它制造从太空探测和跟踪导弹威胁的传感器，并为军方建造和维修侦察机以及无人水面和水下航行器。由于交付的是实体装备，其收入取决于生产计划和硬件订单，而不是长期运行的服务合同。

• Missile-defense sensors导弹防御传感器 — Leidos builds sensors that spot and track missile threats from space, so the military can react faster to an attack.Leidos 制造从太空发现并追踪导弹威胁的传感器，让军方能更快地对攻击做出反应。
• Surveillance planes and sea drones侦察飞机和海上无人器 — Leidos builds and repairs spy planes, and unmanned boats and submarines, that the military uses to watch and patrol land and sea.Leidos 制造和维修侦察飞机，以及军方用来监视和巡逻陆地与海洋的无人船和无人潜航器。
