KBR Company Profile, Products, Employees and Revenue

KBR is one of the largest government services and engineering companies in the US defense market, with roughly $7.7 billion in 2024 revenue and a workforce of around 38,000 people spread across more than 30 countries. The Houston-based firm rarely builds weapons, yet its logistics, engineering and research contracts touch nearly every corner of American military power, from Army supply lines to hypersonic test programs and human spaceflight.

KBR at a glance

What does KBR do

KBR reports through two segments. Government Solutions, by far the larger, handles defense and civil government work across the US, UK and Australia, everything from running base operations and military supply chains to systems engineering, cyber, space domain awareness and test support. Sustainable Technology Solutions licenses process technologies to the chemicals and energy industries, a smaller but high-margin business inherited from the old M.W. Kellogg side of the house.

The defense customer sees KBR mostly as a services integrator. The company sustains Army logistics under LOGCAP, supports NASA astronaut training and space station operations, provides research and engineering manpower for military laboratories, and runs sensitive facilities for intelligence and missile warning customers. Acquisitions such as Centerra in 2020, the UK’s Frazer-Nash Consultancy in 2021 and LinQuest in 2024 pushed the mix steadily toward higher-end engineering and space work.

KBR history from Brown & Root to Halliburton spin-off

The modern company fuses two old names, M.W. Kellogg, a process engineering house founded in 1901, and Brown & Root, a Texas construction firm from 1919 that built warships, bases and much of the US military’s Vietnam-era infrastructure. Both ended up under Halliburton, which merged them into Kellogg Brown & Root in 1998.

The Iraq war made KBR both indispensable and controversial. As the largest contractor supporting deployed US forces, it fed, housed and supplied hundreds of thousands of troops, while drawing years of congressional scrutiny over billing and safety. Halliburton spun KBR off as an independent public company in 2007, and the firm has spent the years since reshaping itself from a wartime logistics giant into a diversified engineering and mission services provider.

KBR military contracts and programs

The common thread is recurring, multi-year services revenue rather than hardware lots. That model produces thinner margins than missile factories but far steadier cash flow, and it scales quickly in a crisis, KBR’s Europe logistics surge after 2022 being the latest example. Peers in this lane include Leidos on the technology side and Babcock International in allied markets.

KBR revenue and financials

KBR reported roughly $7.7 billion in revenue for 2024, up from about $7.0 billion the year before, with Government Solutions contributing on the order of three quarters of the total. The backlog, including options, has hovered around the $20 billion mark, giving unusually long revenue visibility for a services firm. The LinQuest acquisition, at a reported $737 million, added around 1,500 cleared engineers focused on space and air dominance work.

Management has guided toward continued single-digit organic growth, supplemented by bolt-on acquisitions in defense engineering and intelligence. The company sits comfortably inside the top 30 of most global defense revenue rankings, unusual for a firm that ships almost no hardware of its own.

KBR outlook for 2026

Three currents favor KBR into 2026. Sustained US and NATO force posture in Europe keeps LOGCAP task orders flowing, the Pentagon’s test and evaluation push, especially in hypersonics, feeds its research services, and military space budgets keep growing faster than the wider defense topline, a trend visible in awards like Amentum’s NORAD Cheyenne Mountain win that show how fiercely this market is contested. The risk side is equally clear, services contracts recompete constantly, margins are structurally thin, and any drawdown of overseas deployments would bite quickly.

KBR frequently asked questions

What does KBR stand for?

Kellogg Brown & Root, from the 1998 merger of M.W. Kellogg and Brown & Root under Halliburton; the company formally uses just KBR, Inc. today.

Is KBR still part of Halliburton?

No. Halliburton spun KBR off in 2007, and it has traded independently on the NYSE ever since.

How big is KBR?

Roughly $7.7 billion in 2024 revenue and around 38,000 employees across more than 30 countries.

What does KBR do for the US military?

Primarily logistics under LOGCAP, base operations, engineering and test support, intelligence staffing and space-related services, rather than weapons manufacturing.

Does KBR work outside defense?

Yes. Its Sustainable Technology Solutions segment licenses process technology to energy and chemicals customers, and it supports NASA and allied civil agencies.
