Mark Tierney

Mark graduated from the US Naval Academy in 1977 with a B.S. in Operations Analysis. He was the Arleigh Burke Honor Graduate and the Combat Systems Honor Graduate of his Basic Surface Warfare Officer class. In 1988 on USS SIMPSON he directed gun battery counter-fire that resulted in the destruction of a hostile gun battery ashore. He then directed the only surface to surface missile duel in US Navy history, sinking a 1000 ton enemy corvette after it fired a Harpoon missile. He graduated from Naval Postgraduate School (NPS) in 1990 with a Master of Science in Engineering Science, specializing in weapon systems engineering. Upon graduation from NPS he became an Engineering Duty Officer and reported to the Aegis Program Office as the Aegis Baseline Engineer, managing the definition, configuration, and software development of Aegis baselines, managing all Aegis development facilities, and managing HIPER-D, a joint DARPA / Navy program to develop High Performance Distributed Supercomputing for US Navy surface combatants. He then worked in a joint Aegis and PEO Theater Air Defense (TAD) advanced technology program.

His next assignment was to PEO Theater Air Defense, initially managing the development of the Advanced Combat Direction System (ACDS) Block 1 (an ACAT 2 program). His responsibilities soon grew to include the development and life cycle support for all non-Aegis shipboard combat systems, including ACDS Block 0 (ACAT 2), NTDS, NTU cruisers, FFG’s, and Ship Self Defense System (SSDS, another ACAT 2 program).

He then served as the PEO TAD lead for the combat system on DDG 1000 before retiring from the Navy in 1997 and accepting a position with Ocean Systems Engineering Corporation (OSEC) in San Diego. At OSEC, he provided full time engineering and programmatic support to PMW 163 (now PMW 120) in the development of advanced technologies for signals intelligence. Under his leadership, OSEC business with SPAWAR and associated Program Executive Offices grew from zero to $22M per year. When QinetiQ North America (QNA) purchased OSEC and ComGlobal Systems, Mark became responsible for the combined OSEC and ComGlobal operations supporting SPAWAR and eventually also for support services to Office of Naval Research (ONR), NAVSEA, and the US Coast Guard.

Leaving QNA, Mark founded E3R in June 2011. Mark is certified as a DAWIA Level 3 Program Manager and was awarded the Assistant Secretary of the Navy Acquisition Reform Award and Bronze Star with Combat “V”.
