The AN/PSQ-42 Enhanced Night Vision Goggle-Binocular (ENVG-B) is a third-generation passive binocular night vision device developed for the United States Army by L3Harris. It combines dual tube image-intensifying (I²) and thermal-imaging technologies into a single goggle, enabling vision in low-light conditions. The two methods can be used individually or simultaneously in a fused mode.[1] The ENVG-B is intended to be issued to the dismounted combat arms soldiers within the Army's Brigade combat teams (BCT), and so far over 10,000 have been issued to several BCT's within the 1st Infantry Division, 2nd Infantry Division, 25th Infantry Division, 82nd Airborne Division and 101st Airborne Division.[2][3] The US Marine Corps has also purchased 3,100 ENVG-B units.[4]
Development[edit]
The ENVG-B was reported to be in development as early as 2018, intended to give soldiers better depth perception than the monocular AN/PVS-14 and AN/PSQ-20.[5] Initial production (Directed Requirements Contract) goggles were produced with a black housing, while full rate production (Program of Record Contract) goggles are now produced in a Tan 499 housing.[6]
Design and features[edit]
The AN/PSQ-42 Enhanced Night Vision Goggle-Binocular combines two image intensification tubes with an uncooled thermal imager and is able to operate in an I²-only mode or a fusion mode that combines I² with a thermal image overlay. The overlay is also capable of displaying a compass and augmented reality data from a Nett Warrior device. The ENVG-B can also display wirelessly transmitted weapon sight crosshair and thermal imagery from the Family of Weapon Sights-Individual (FWS-I) thermal imager mounted on a weapon.[7][8] The image-intensifying tubes also allows the user to illuminate, designate, and engage targets conventionally with weapon-mounted infrared laser pointer-illuminator devices such as the AN/PEQ-15.
The entire ENVG-B assembly consists of the ENVG-B goggles themselves, Positioning Assembly (PA), Helmet Mount Assembly (HMA) and battery pack.[9] In a fashion similar to the AN/PSQ-20 and AN/PVS-31, the ENVG-B does not receive power from a battery within the goggle housing itself (such as in the AN/PVS-14). Instead, the goggle receives power from the battery pack mounted on the rear of the soldier's helmet via a circuit that traverses the HMA and PA, with hotshoe connectors at the interface between those components.[8] This shifts the center mass of an ENVG-B equipped helmet toward the wearer's neck, resulting in a more ergonomic balance and reducing neck strain, especially in the prone. The ENVG-B assembly can be mounted on the ACH, ECH and IHPS helmets. A special helmet cover designed to conceal the battery pack and HMA exists for these helmets.[8]
A small infrared illuminator is built into the housing for viewing handheld items like a map, weapon, or radio. A gain control knob is centrally mounted on the bridge of the goggle housing. Both the eyepieces and objective lenses are capable of affixing a protective sacrificial lens, and the objective lenses have removable protective rubber caps with lanyards.
Operational history[edit]
The ENVG-B saw its first operational use with 1st Brigade, 82nd Airborne Division during its participation in Operation Allies Refuge in August 2021.
