If the federal government were a company, it would be among the biggest in the world — with a budget in excess of $4 trillion a year. However, despite its enormous size, the mind-bogglingly vast array of responsibilities the government has means that it can’t possibly handle them all itself. As such, the United States government — like many others across the globe — farms out a great deal of tasks to privately held companies.

And while some people might feel a little uncomfortable about the private sector being invited into the public, the reality is that everything from the electricity running in your house to the high-tech fighter jets keeping you safe relies heavily on the support of private companies. So, here’s a closer look at some of the important ways contractors step in to help the government.

1. Building the Military

A quick look at the biggest federal contractors for the U.S. government for 2017 should make it clear just how interlinked private companies are to our public defense. The top five government contractors — Lockheed Martin, Boeing, General Dynamics, Raytheon and Northrop Grumman — have some $115.2 billion obligated to them for some 215,896 different actions, including the design and construction of much of the nation’s Air Force.

The military even relies on private military companies to provide soldiers in some circumstances. In fact, the U.S. is the world’s largest user of private military and security forces, which are employed in a variety of capacities, including protecting U.S. diplomatic personnel for the Department of State. The practice is one that has stoked some controversy, though, over how much government oversight is exerted over private security companies like G4S or MVM.

2. Traveling to Space

NASA officially ended its space shuttle program in 2011, ending about a half-century of space exploration done solely at the government’s behest. But that doesn’t mean the United States is out of the space game. There are private space companies like Elon Musk’s SpaceX or Jeff Bezos’ Blue Origin that are designing and building reusable rockets that will hopefully allow them to act as contractors for delivering payloads — and maybe tourists — into the great beyond.

3. Providing Utilities

Utilities present an interesting economic problem. The infrastructure cost of building massive networks of power plants, transformers and power lines (or reservoirs, water pumps, pipes and sewage treatment plants, for that matter) is too high to expect competing companies to exist, but the services they provide are too important to leave to a series of local monopolies. That’s why most Americans have utilities provided by private companies that are themselves overseen by a public utilities commission that carefully regulates rates to ensure consumers are protected. So while turning on the lights is a service protected by the government, there are also some 11 different companies in the S&P 500 that make their money providing services like water and power.
