Robert Watkins

Chairman and Founder

Nominated for a Bronze Star.
An Army Commendation Vietnam Veteran, in 1971 Robert founded an airport refueler maintenance company which grew into 14 major city markets. In 1979 he founded a second company manufacturing aircraft refuelers known as Rampmaster; followed by a 3rd leasing company/partnership with a GE Capital Corp.

In 2009, Robert was also associated with a 4^th startup of an East Coast OEM aircraft completion center.

Rampmaster primarily began as an American Story based upon four launch patents which he holds.  The company now holds 13 patents including a self-sustaining, electric hydrant cart that regenerates its own emission free power, and patented “Engine Management” that dramatically reduces fuel consumption costs and carbon emissions while the fuel trucks are re-filling airliners.

Rampmaster built and leased more large airline refuelers than anyone on any continent, at any time anywhere, or about 80% domestic market share.  The current fleet is active at all major airports, delivering up to 80 million barrels of jet fuel a year, or about 12% of total USA demand. 

An accomplished pilot for over 60 years, Robert still flies a Learjet 60 worldwide and is a certified recipient of the FAA Master Pilot award.  He also holds a Christian Ministry ordination originated from Gospel Crusade Ministry Forum Int. associated with over 1,000-member family of churches worldwide. 

Robert and family have performed repeated missionary work part time into eastern Nigeria and run a private foundation supporting both International and Domestic ministries. 

He has two sons, one daughter and, eleven grandchildren.
