Dec 16 (Reuters) - Lockheed Martin (LMT.N) said on Monday it had formed a subsidiary that will help U.S. defense companies incorporate artificial intelligence into their operations.

Companies across sectors have leaned more on AI over the past few years to help optimize their workflow. However, defense companies have remained cautious given the sensitive data required to train models in the sector.

Earlier this month, privately held defense tech company Anduril Industries partnered with ChatGPT-maker OpenAI to develop and deploy advanced artificial intelligence solutions for national security missions.
