The American Blimp MZ-3A is a blimp owned by the United States Navy from 2006 to 2017. It is a modified American Blimp Corporation A-170 series commercial blimp and given the USN type/model/series (T/M/S) designation MZ-3A and Bureau Number (BuNo) 167811. After delivery to the Navy, the airship began operations as an advanced flying laboratory used to evaluate affordable sensor payloads, the development of new lighter-than-air (LTA) technologies and general flight support for other related research and development/science and technology (R&D/S&T) projects. It was the last airship to be operated by the U. S. military. Description The airship is propeller-driven by two Lycoming engines, providing a maximum cruise speed of just under . The manned 178-foot LTA craft has an operational payload capability of up to and can remain aloft and nearly stationary for more than twelve hours, performing various missions in support of technology development for Command, Control, Communications, Computers, Intelligence, Surveillance and Reconnaissance (C4ISR) concepts. History In May 2006, Air Test and Evaluation Squadron TWENTY, Lighter-than-Air Vehicle (LTAV) Detachment (VX-20 LTAV Det) began regular flight operations from Naval Air Engineering Station Lakehurst located in Lakehurst, New Jersey. In 2007 flight operations were halted and the ship stored in Hangar Six at NAES Lakehurst. In October 2009, the MZ-3A was transferred to the United States Naval Research Laboratory Military Support Division's Scientific Development Squadron One (VXS-1), formerly known as the Flight Support Detachment, located at Naval Air Station Patuxent River, Maryland. In March 2010 the airship resumed flight operations with test flights at Marine Corps Air Station Yuma, Arizona. The MZ-3A is a government owned / contractor operated (GOCO) aircraft operated by a civilian contractor, Integrated Systems Solutions, Inc. (ISSI) of California. ISSI currently maintains and operates the vehicle employing Navy approved, highly qualified, commercial blimp pilots to command the airship. On 5 July 2010, the MZ-3A was re-deployed to the Jack Edwards National Airport in Gulf Shores, Alabama to assist in the Deepwater Horizon oil spill recovery operation. At a ribbon-cutting ceremony on 26 October 2011 at the Naval Air Warfare Center Aircraft Division, NAES Lakehurst, New Jersey, and in recognition of the Centennial of Naval Aviation, the Navy unveiled a fresh identity for the MZ-3A. Emblazoned with red, white and blue striped rudders reminiscent of the Navy's airships just prior to World War II, the airship also carries the insignia of the VXS-1 Warlocks and the banner
