W1 Main Circuit (1MC) is the term for the shipboard public address circuits on United States Navy and United States Coast Guard vessels. This provides a means of transmitting general information and orders to all internal ship spaces and topside areas, and is loud enough that all embarked personnel are able to (normally) hear it. It is used to put out general information to the ship’s crew on a regular basis each day. The system consists of an amplifier-oscillator group which is located in the IC/gyro room, a microphone control station, portable microphones at each control station and loudspeakers located throughout the ship. Control stations for the 1MC announcing system are located at the pilot house, OOD stations on the quarterdecks, aft steering and Damage Control Central area.
WThe AN/AWG-9 and AN/APG-71 radars are all-weather, multi-mode X band pulse-Doppler radar systems used in the F-14 Tomcat, and also tested on TA-3B. It is a very long-range air-to-air system with the capability of guiding several AIM-54 Phoenix or AIM-120 AMRAAM missiles at the same time using its track while scan mode. The primary difference between the AWG-9 and APG-71 is the replacement of the former's analog computer with all-digital computer. Both the AWG-9 and APG-71 were designed and manufactured by Hughes Aircraft; contractor support is now being provided by Raytheon. The AWG-9 was originally developed for the failed naval F-111B program.

WNavy eReader Device, or NeRD, is an e-reader developed by the United States Navy's General Library Program for use aboard its submarines. Released in May 2014, it gives sailors accessibility to the Navy's library and various books while on a submarine that has limited storage space for paper books; sailors are normally on a six-month deployment and have some downtime for reading. Each submarine is assigned five NeRDs. In late 2014, the Navy started released the device to its surface fleet, distributing over 1,170 NeRDs.
WThe NOTS-EV-1 Pilot, better known as NOTSNIK was an expendable launch system and anti-satellite weapon developed by the United States Navy's United States Naval Ordnance Test Station (NOTS). NOTSNIK began as an in-house project using available NOTS funds. The Advanced Research Projects Agency later supplied some funds for the program. The program involved creating transisterised sensors to detect nuclear explosions from the Operation Argus tests. Ten were launched during July and August 1958, all of which failed. It was the first air-launched rocket to be used for an orbital launch attempt; however, none was recorded as having reached orbit. Following the third orbital launch attempt a NOTS engineer at the tracking station in Christchurch, New Zealand reported receiving a weak signal from the spacecraft; This was never confirmed, and the launches were not catalogued as having reached orbit. The Pilot rocket was part of Project Pilot.
WThe NOTS-EV-2 Caleb, also known as NOTS-500, Hi-Hoe and SIP was an expendable launch system, which was later used as a sounding rocket and prototype anti-satellite weapon. It was developed by the United States Navy's Naval Ordnance Test Station (NOTS) as a follow-up to the NOTS-EV-1 Pilot, which had been abandoned following ten launches officially classified as failed missions. Two were launched in July and October 1960, before the cancellation of the project. Following cancellation, two leftover Calebs were used in the Satellite Interceptor Program (SIP), while three more were used as sounding rockets, under the designation Hi-Hoe. These derivatives flew until July 1962, when the Hi-Hoe made its final flight.
WAn oxygen breathing apparatus (OBA) is a rebreather. It is used primarily in firefighting. Its oxygen is generated by chemicals contained in the green canister, which is inserted at the base of the breathing device. The canister uses potassium superoxide as both a CO2 scrubber and an O2 generator. A sodium chlorate candle in the base generates additional oxygen when first beginning use as the canister has to achieve a high internal temperature before it will start generating oxygen on its own. It is the circulation of exhaled air through the canister that starts the chemical process, usually taking less than five minutes, the normal burn time of the "candle" and the mask will initially fill with a light, harmless smoke. The extreme heat of the chemical reaction requires the use of thick leather gloves for handling spent canisters. The bags along either side of the chest unit cool the air mixture before inhalation and is a surprisingly effective system, with the air being quite cool when entering the face mask. There is a 60-minute timer at the top of the chest unit which, during the fighting of a casualty, is set for only 45 minutes. This would give the user a 15-minute window to evacuate to a safe atmosphere. Though it looks bulky and unwieldy it is a light and comfortable device to wear and does not much interfere with the user's freedom of movement.
WThe Ford Aerospace AN/AVQ-10 Pave Knife was an early targeting pod developed by the USAF and US Navy to designate and guide laser-guided bombs.
WPrairie-Masker is a radiated noise reduction system fitted to some western warships, including the Spruance, Oliver H.
