In order to carry out successfully and speedily all these duties large increases in personnel, in ships of all classes and in the instrumentalities needed for their production and service were demanded. Briefly, then, it may be stated that on the day war was declared the enlistment and enrollment of the navy numbered 65,777 men. On the day Germany signed the armistice it had increased to 497,030 men and women, for it became necessary to enroll capable and patriotic women as yeomen to meet the sudden expansion and enlarged duties imposed by war conditions. This expansion has been progressive. In 1912 there were 3,094 officers and 47,515 enlisted men; by July 1, 1916, the number had grown to 4,293 officers and 54,234 enlisted men, and again in that year to 68,700 in all. In granting the increase Congress authorized the President in his discretion to augment that force to 87,800. Immediately on the outbreak of the war the navy was recruited to that strength, but it was found that under the provisions of our laws there were not sufficient officers in the upper grades of the navy to do the war work. At the same time the lessons of the war showed it was impossible to have the combatant ships of the navy ready for instant war service unless the ships had their full personnel on board and that personnel was highly trained.
In addition to this permanent strength recourse was had to the development of the existing reserves and to the creation of a new force.
NAVAL VOLUNTEERS
Up to 1913 the only organization that made any pretense of training men for the navy was the Naval Militia, and that was under State control, with practically no Federal supervision. As the militia seemed to offer the only means of producing a trained reserve, steps were at once taken to put it on a sound basis, and on February 16, 1914, a real Naval Militia under Federal control was created, provision being made for its organization and training in peace, as well as its utilization in war. As with all organized militia, the Naval Militia, even with the law of 1914, could not, under the Constitution, be called into service as such except for limited duties, such as to repel invasion. It could not be used outside the territorial limits of the United States. It is evident, then, that with such restrictions militia could hardly meet the requirements of the navy in a foreign war, and to overcome this difficulty the "National Naval Volunteers" were created in August, 1916.
Under this act members of Naval Militia organizations were authorized to volunteer for "any emergency," of which emergency the President was to be the judge. Other laws included the same measure, provided for a reserve force, for the automatic increase of officer personnel in each corps to correspond with increases in enlisted men, and for the Naval Flying Corps, special engineering officers, and the Naval Dental and Dental Reserve Corps. It also provided for taking over the lighthouse and other departmental divisions by the navy in time of war. Briefly, then, on July 1, 1917, three months after the declaration of war, the number of officers had increased to 8,038—4,694 regulars, 3,344 reserves—and the number of enlisted men to 171,133—128,666 regulars, 32,379 reserves, 10,088 National Naval Volunteers. The increase since that time is as follows:
| April 1, 1918 | Officers | Men |
| Regular Navy | ||
| Permanent | 5,441 | 198,224 |
| Temporary | 2,519 | |
| Reserves | 10,625 | 85,475 |
| Total | 18,585 | 283,699 |
| November 9, 1918 | ||
| Permanent | 5,656 | 206,684 |
| Temporary | 4,833 | |
| Reserves | 21,985 | 290,346 |
| Total | 32,474 | 497,030 |
THE NAVY THAT FLIES
The expansion of aviation in the navy has been of gratifying proportions and effectiveness. On July 1, 1917, naval aviation was still in its infancy. At that time there were only 45 naval aviators. There were officers of the navy, Marine Corps, and Coast Guard who had been given special training in and were attached to aviation. There were approximately 200 student officers under training, and about 1,250 enlisted men attached to the Aviation Service. These enlisted men were assigned to the three naval air stations in this country then in commission. Pensacola, Fla., had about 1,000 men, Bay Shore, Long Island, N.Y., had about 100, and Squantum, Mass., which was abandoned in the fall of 1917, had about 150 men. On July 1, 1918, there were 823 naval aviators, approximately 2,052 student officers, and 400 ground officers attached to naval aviation. In addition, there were more than 7,300 trained mechanics, and more than 5,400 mechanics in training. The total enlisted and commissioned personnel at this time was about 30,000.
THE SHIPS
On the day war was declared 197 ships were in commission. To-day there are 2,003. In addition to furnishing all these ships with trained officers and men, the duty of supplying crews and officers of the growing merchant marine was undertaken by the navy. There has not been a day when the demand for men for these ships has not been supplied—how fit they were all the world attests—and after manning the merchant ships there has not been a time when provision was not made for the constantly increasing number of ships taken over by the navy.
