In Gray Lensman, Port Admiral Haynes noted that, were it not for the galactic war, a financial crisis might have risen over the Patrol possessing so much in the way of legal tender. (For comparison, in 1940, the year after Gray Lensman was originally published, the U. S. Gross Domestic Product was $97 billion, so the "ten thousand million credit" figure was perceived by readers as equivalent to 10% of GDP; in 2008 terms that would be almost $1.5 trillion.) Also, the Patrol was well equipped for its second role as military force. In Galactic Patrol it fielded a Grand Fleet of over fifty thousand capital ships, including large numbers of "maulers", or super-heavy battleships. That fleet grew by leaps and bounds through the later novels, numbering well into the millions by Second Stage Lensmen and Children of the Lens. The number of combat units in the Grand Fleet were so numerous that a special flagship, the Directrix or Z9M9Z, had to be commissioned with extensive and advanced C3. It is explicitly stated in later novels that the Directrix/Z9M9Z is in command of "one-million combat units", which is further elaborated upon as literally one-million individual fleets. The exact number of ships in each fleet is unknown, but the defensive fleet for Directrix alone was eighty ships, and this could reasonably be said to be the number of other fleets—or approximately 80,000,000 ships in total. This also leads to a fair estimation of the size of Civilization, since each fleet was based on an individual member-world of Civilization, indicating about one-million planets in total. This number does not include a fleet of uninhabited planets converted into mobile, armored weapons (also explicitly mentioned) and a huge, planet sized, antimatter WMD called a "Negasphere". This number is in keeping with the fact that, later in the series, Boskone (the great enemy of Civilization) mustered fleets of warships and mobile worlds of comparable size to be sent through the "hundreds of thousands" of hyperspatial tubes they'd opened to attack Arisia and Earth directly. It is possible then that at that one battle Boskone possessed millions or even tens of millions of ships equal in size and power to super-maulers, thus explaining Civilization's need for such astonishingly vast standing armed forces. The Patrol's ground forces, while receiving less attention than the fleet, were no slouches either. Perhaps the most visible of the ground combat arm
