SCIENTIFIC AMERICAN MUNN & CO. Editors and Proprietors No. 361 Broadvve.y New York NEW YORK SATURDAY JANUARY 31 1903. WEIGHT AND VELOCITY IN HEAVY GUNS. Elsewhere in this issue we give illustrations of the successful tests recently carried out with the new army 16-inch gun tests which prove it to be the most powerful weapon in existence exceeding greatly in years before. Whether in comparison with modern ordnance it is the most efficient piece relatively to its weight and cost is another question to which even the gentlemen who designed and built it would prob ably return a negative answer. In defining the ques tion of relative efficiency however it should be men tioned that the 16-inch gun was designed several years ag and therefore cannot be said to represent the very latest developments in ordnance. The tendency to-day is toward reduced weight of gun and projectile and increased muzzle velocity. As we have shown very clearly in the data of the Krupp gun of the 1901 pat tern (included in the table shown on another page) although the weight of the Krupp piece is only about projectile is about 40 per cent as heavy its high muz zle velocity of 3330 foot-seconds gives the shell a muzzle energy of 59280 tons or between 3000 and 4000 foot-tons greater than that of the Armstrong piece and 75 per cent of that of our own gun. The muzzle energy per ton-weight of gun moreover reaches the high figure of 1029 foot-tons. It is interesting to notice that the increase which is made in the length of the bore as compared with the older guns with a view to obtaining the full ballistic value of the rela tively small powder charge is so great that the smaller gun is actually the longest of the three longer even by a few inches than the great 16-inch gun now at Sandy Hook. This comparison is given simply to il lustrate the advance which has been made in heavy ordnance since the plans of the English gun and later of our army 16-inch gun were drawn up; for as the tests on Saturday clearl
