THE USN PROVIDED
INFORMATION TO THE OFFICERS
In order for the officers and men of the USN to have the best Gunnery and Fire Control Systems the USN provided the very best Naval Ordnance
text books and schools for the men of the USN.
The Naval Ordnance text books cover every aspect of USN gunnery and Fire Control down to the smallest detail and contain all of the data needed
for each ship to be proficient in gunnery.
One of the things needed in gunnery is gun powder and it must be of the highest quality.
One of the duties of Dalghren was to test all powder to make sure that it would preform as required in USN guns in the fleet.
The powder was so perfect that you can read all of the USN Naval Ordnance books that the USN printed and you will not find any mention of the
powder causing any variation in gun IV when the powder comes from the same lot of powder or from different lots of powder made for the same
The USN Naval Ordnance books tell you that the only things that change gun IV when using powder from the same lot is barrel wear, projectile
weight and powder temperature.
If the powder within the same lot had caused any variation in gun IV when firing the same gun with the same weight projectile then there would
have been a lot of written data an the subject.
There is no written data on the subject in any USN Naval Ordnance book as this does not occur.
