The YF-23 prototypes are 67.4 feet in length and have wingspans of 43.6 ft. During the Advanced Tactical Fighter program, one YF-23 was powered by twin Pratt and Whitney YF119 turbofan engines, while the other had two General Electric YF120 turbofan engines installed. The aircraft achieved a speed of around Mach 1.8 throughout the program.
Two Pratt & Whitney F119-PW-100’s of approximately 35,000 lbs. thrust each with afterburner or two General Electric F120-GE-100 turbofans.
Sea Shadow is a test craft developed under a combined program by the Advanced Research Projects Agency (ARPA), the Navy, and Lockheed Martin Missiles and Space Company. The Sea Shadow program was begun in the mid-1980s. Its purpose is to explore a variety of new technologies for surface ships, including ship control, structures, automation for reduced manning, seakeeping and signature control. In 1993-1994, the craft was revealed to the public and underwent daylight testing. Since 1994, Sea Shadow has been maintained in a lay-up status and is currently homeported at Naval Station San Diego. In anticipation of conducting future ship research and development testing, the U.S. Navy reactivated the Sea Shadow craft in early 1999. Sea Shadow will support risk reduction for future surface ship platforms such as DD 21, the Navy’s 21st Century Land Attack Destroyer. The platform will allow the Navy to explore and test, in a realistic at-sea environment, important DD 21 advanced information and automation technologies that support reduced manning and ship survivability.
The Multifunctional Utility/Logistics and Equipment (MULE) Vehicle is a 2.5-ton Unmanned Ground Vehicle (UGV) that will support dismounted and air assault operations. The MULE is sling-loadable under military rotorcraft and features three variants sharing a common chassis: transport, countermine and the Armed Robotic Vehicle (ARV)-Assault-Light (ARV-A-L).
The XM1217 Transport MULE Vehicle (MULE-T) carries 1,900-2,400 pounds of equipment and rucksacks for dismounted infantry squads. The rugged vehicle relieves Soldiers of heavy equipment and packs while following them through complex terrain.
Thank you, Chive, for once again posting some cool stuff. I stole this from you to keep it as a key for my future build. Although I think I’m going to go much more modern and use many more containers.
Last weekend I put this backpack through a test and I am happy to say that it did very well. I purchased this backpack for my trip to Thailand to keep stuff dry as we walk around in the rain, so canyoneering near Payson, AZ was a good way to test it.
Thank you Chive for this one! Very cool.
