M107 projectile
The M107 155mm projectile was the standard 155mm high explosive (HE) projectile for howitzers of the US Army and US Marine Corps'. A bursting round with fragmentation and blast effects (range is not known), the M107 is being superseded in the US military by the M795.
Development
The M107 is a development of the M102 155mm mm shell that was developed in the 1930s from the French Schneider 155 mm projectile for the Model 1917 Howitzer. The M107 differs from the M102 mainly in having a wider driving band.
The M102 shell was modified in 1944 to accommodate VT fuzes. This required a deeper fuze well. However since most fuzes did not require such a deep cavity, a small aluminium-wrapped 136 g TNT supplemental charge is fitted in the space.
Description
The body consists of a hollow steel shell containing high explosive (either TNT or Composition B) painted olive drab with yellow markings. A fuze adapter is screwed into the body and brazed in place. An eyebolt lifting plug is screwed into the fuze well to assist in transportation. The plug is removed and replaced with a fuze for firing. The complete projectile weighs 43.2 kg, is 800 mm long and contains 15.8% explosive by weight. It is a separate-loading projectile—propellant bags or MAC charges are loaded separately.
Messier 107
Globular Cluster M107 (also known as Messier Object 107 or NGC 6171) is the last globular cluster in the Messier Catalogue. It is a very loose globular cluster in the constellation Ophiuchus. It was discovered by Pierre Méchain in April 1782 and independently by William Herschel in 1793. It wasn't until 1947 that Helen Sawyer Hogg added it and three other objects discovered by Méchain to the list of Messier objects.
M107 is close to the galactic plane at a distance of about 20,900 light-years from Earth. There are 25 known variable stars in this cluster.
