10 In the Lockheed-Martin F-22 Raptor Advanced Tactical Fighter, 42% of the structural weight consists of titanium. The Materials Information Society, Introduction to Selection of Titanium Alloys, ASM International, 2002

11 The Ultra-light weight Field Howitzer, designated M777A1 in the USA was selected in 1997 by a joint US Army/Marine Corps initiative to replace the existing inventory of M mm towed howitzers. The construction of the M777A1 makes extensive use of titanium and titanium castings, enabling a weight reduction of 3,175kg compared to the M198 howitzer which it replaces in the US Army and USMC inventory.
