Boeing once proposed the BC-17X , a commercial version of the C-17 Globemaster III. Designed to deliver outsized cargo to remote, unpaved airfields, it was intended to earn money commercially while being available to the military as needed.

By mimicking the hexagonal, "brick-and-mortar" structure of nacre at a microscopic level, the new material can absorb energy from cracks and slow their spread, rather than shattering.

Since cement production accounts for roughly 8% of global greenhouse gas emissions , making it 17 times more durable could significantly reduce waste and the need for frequent replacements. 17x in Military & Aerospace Boeing once proposed the BC-17X , a commercial

The designation "17X" also holds weight within specialized military career fields and aircraft development.

Scientists looked at nacre (mother-of-pearl), the inner layer of oyster shells, which is incredibly resistant to cracking despite being made of brittle minerals. Since cement production accounts for roughly 8% of

Recently, the Marine Corps Operation StormBreaker successfully overhauled software delivery timelines, slashing them by a factor of 17 to better support digital capabilities in the field. 17x in Social & Scientific Research

In the Air Force, "17X" is the career field identifier for Cyberspace Operations Officers . These professionals are tasked with managing the "warfighter mindset" across cyber terrains such as aircraft and industrial control systems. the inner layer of oyster shells

Perhaps the most significant recent use of "17x" is in the field of sustainable construction. Researchers at have developed a bio-inspired cement paste that is approximately 17 times tougher than standard cement.
