Google executives announced to company staff this morning that the tech giant won’t renew its contract to work on Project Maven, the controversial Pentagon program designed to provide the military with artificial intelligence technology used to help drone operators identify images on the battlefield. Google will continue work on the project through March 2019, according to multiple people with knowledge of the announcement, but once the 18-month contract concludes, it will not be renewed. The company, however, has not committed to forego signing other military contracts dealing with artificial intelligence, according to multiple people with knowledge of the decision. Google declined to comment for this story.

Google has not committed to forego signing other military contracts dealing with artificial intelligence.

The announcement was made by Diane Greene, chief executive of Google’s cloud business, at a Friday morning all-hands briefing for the Google Cloud team, which is known internally as the “weather report.” Google faced growing pressure since the contract was revealed by Gizmodo and The Intercept in March. Nearly a dozen employees resigned in protest, and several thousand signed an open letter declaring that “Google should not be in the business of war.” More than 700 academics also signed a letter demanding that “Google terminate its contract with the DoD, and that Google and its parent company Alphabet commit not to develop military technologies and not to use the personal data that they collect for military purposes.”

The Defense Department has hoped to harness the latest advancements from Silicon Valley. The Defense Innovation Board, an arm of the Pentagon that makes technological recommendations, declared that winning the global race to adopt artificial intelligence was as important as “nuclear weapons in the 1940s and with precision-guided weapons and stealth technology afterward.” Project Maven was the military’s first major effort to collaborate with tech firms to deploy AI technology. The program was launched last year. In the bidding process, companies were asked to help devise a machine learning technology that could help drone analysts interpret the vast image data vacuumed up from the military’s fleet of 1,100 drones to better target bombing strikes against the Islamic State.
