16 January 
Parachutes issued for heavier-than-air
 
use-The Bureau of Aeronautics directed that Army- 
type seat pack parachutes be shipped to Marine Corps 
aviation units in Haiti, the Dominican Republic, Guam 
and Quantico, Va. 
6 February 
The Washington Treaty, limiting naval
 
armament, was signed in Washington, D.C., by repre- 
sentatives of the British Empire, France, Italy, Japan 
and the United States. The treaty established a tonnage 
ratio of 5-5-3 for capital ships of Great Britain, the 
United States and Japan respectively, and a lesser fig- 
ure for France and Italy. The same ratio for aircraft 
carrier tonnage set overall limits at 135,000-135,000- 
81,000 tons. The treaty also limited any new carrier to 
27,000 tons with a provision that, if total carrier ton- 
nage were not exceeded thereby, nations could build 
two carriers of not more than 33,000 tons each or 
obtain them by converting existing or partially con- 
structed ships which would otherwise be scrapped by 
this treaty. 
7 February 
The completion of a 50-hour test run of
 
the Lawrance J-1, 200-hp, radial aircooled engine by 
the Aeronautical Engine Laboratory, Washington Navy 
Yard, D.C., foreshadowed the successful use of radial 
engines in naval aircraft. 
2 March 
Experimental investigation and develop-
 
ment of catapults using gunpowder was initiated, 
eventually producing a new type catapult for use in 
launching aircraft from capital ships. 
20 March 
Langley, 
converted from the collier 
Jupiter
 
(AC 3) as the first carrier of the U.S. Navy, was com- 
missioned at Norfolk, Va., under command of her 
Executive Officer, Commander Kenneth Whiting.

Research Laboratory as had been provid-
 
ed for in a public law passed in August 1916. 
Following the construction of necessary buildings at 
Bellevue, D.C., the Aircraft Radio Laboratory from NAS 
Anacostia, D.C., the Naval Radio Research Laboratory 
from the Bureau of Standards and the Sound Research 
Section of the Engineering Experiment Station were 
consolidated at the new organization prior to its estab- 
lishment in July 1923. In view of the research orienta- 
tion of this facility, it was generally called the Naval 
Research Laboratory, and its name was officially 
changed to that by the Naval Appropriations Act of 
1926. 
27 March 
To comply with a provision of the law
 
establishing the Bureau of Aeronautics that its chief 
and at least 70 percent of its officers be either pilots or 
observers, the Bureau of Aeronautics defined the func- 
tions and qualifications of Naval Aviation Observers, 
and recommended a course of study for their training. 
Upon its approval by the Bureau of Navigation, Rear 
Admiral William A. Moffett reported for training, and 
on 17 June 1922 qualified as the first Naval Aviation 
Observer. 
29 March 
A change in the aircraft designation sys-
 
tem was promulgated which added the identity of the 
manufacturer to the model designation. Symbols con- 
sisted of a combination of letters and numbers in 
which the first letter identified the manufacturer and 
the second, the class (or mission) of the aircraft. Thus 
MO was a Martin observation plane. Numbers appear- 
ing between letters indicated the series of designs 
within the class built by the same manufacturer (the 1 
being omitted) and numbers following a dash after the 
class letter indicated modifications of the basic model. 
Thus, the second modification of the MO became MO- 
2, while the second-design observation plane built by 
Martin became M20.
