Description:Protecting what matters most is the mission that matters most.
As we journey through a new era of space, Lockheed Martin Space is a pioneer, partner, innovator and builder. Our amazing team is on a mission to make a difference in the world. Every day, our 115,000 employees come to work with one focus - our customers' hardest missions. Those that demand extraordinary amounts of courage, resilience, and precision. They're dangerous. Critical. Sometimes they even provide an opportunity to change the world and save lives. Those are the missions we care about. We provide the resources, inspiration and focus and if you have the passion and courage, we want to build a better tomorrow with you!
Defending against modern-day missile threats requires constant collaboration and innovation. We're able to integrate systems from end to end to detect, control, and engage the full spectrum of missile threats across every domain. It's why we're investing in disruptive technology like directed energy, space-based capabilities, and solid-state radar. We're creating layers of defense that help keep us all safe and protect our freedoms.
Shooting a missile down with a missile was once a concept only dreamed up in science fiction novels. We've made it a scientific fact! So what does it take to spot an enemy missile launch, identify its intended target, calculate its exact trajectory, launch an interceptor, and guide it to destroy the threat in mid-air in a matter of seconds? It's not easy - but at Lockheed Martin, we help customers solve the world's most complex challenges. Our culture supports employees to dream big, perform with perfection, and create incredible products. Come, join us!
