The Gulfstream V (Model GV, pronounced "G-five") is a large, long-range business jet aircraft produced by Gulfstream Aerospace, derived from the previous Gulfstream IV.It flies up to Mach 0.885 (508 kn; 940 km/h), up to 51,000 feet (16,000 m) and has a 6,500 nmi (12,000 km) range.
This is a list of United States Army fire control, and sighting material by supply catalog designation, or Standard Nomenclature List (SNL) group "F".The United States Army Ordnance Corps Supply Catalog used an alpha-numeric nomenclature system from about the mid-1920s to about 1958.

A laser rangefinder, also known as a laser telemeter, is a rangefinder that uses a laser beam to determine the distance to an object. The most common form of laser rangefinder operates on the time of flight principle by sending a laser pulse in a narrow beam towards the object and measuring the time taken by the pulse to be reflected off the ...
Eyepiece image of a naval rangefinder, showing the displaced image when not yet adjusted for range. The coincidence rangefinder uses a single eyepiece. Light from the target enters the rangefinder through two windows located at either end of the instrument. At either side the incident beam is reflected to the center of the optical bar by a ...
The Electro 35 is a rangefinder camera made by Japanese company Yashica from the mid-1960s with a coupled and fixed 1:1.7 45 mm lens. It was the first electronically controlled camera, operating mainly in an aperture priority 'auto' mode.
5-inch (127 mm) gun on the Fletcher-class destroyer USS David W. Taylor. Stabilizing signals from the Stable Element kept the optical sight telescopes, rangefinder, and radar antenna free from the effects of deck tilt. The signal that kept the rangefinder's axis horizontal was called "crosslevel"; elevation stabilization was called simply "level".
The exposure meter uses a PX625 mercury battery, which is now discontinued.The alkaline equivalent can be used, but the different voltage, different discharge curve, and absence of voltage regulation circuit cause incorrect metering that results in between 1.5-f-stop underexposure at the beginning of the life of the alkaline battery and 1.5-f-stop overexposure at the end.
