The use of Light Amplification by Stimulated Emission of Radiation (i.e., LASERs or lasers) by the U.S. Department of Defense is not new and includes laser weapons guidance, laser-aided measurements, and even lasers as weapons (e.g., Airborne Laser). Lasers in the support of telecommunications is also not new. The use of laser light in fiber optics has shattered thoughts on communications bandwidth and throughput. Even the use of lasers in space is no longer new. Lasers are being used for satellite-to-satellite crosslinking. Laser communication can transmit orders-of-magnitude more data using orders-of-magnitude less power and can do so with minimal risk of exposure to the sending and receiving terminals. What is new is using lasers as the uplink and downlink between the terrestrial segment and the space segment of satellite systems. More so, the use of lasers to transmit and receive data between moving terrestrial segments (e.g., ships at sea, airplanes in flight) and geosynchronous satellites is burgeoning. This manuscript examines the technological maturation of employing lasers as the signal carrier for satellite communications linking terrestrial and space systems. The purpose of the manuscript is to develop key performance parameters (KPPs) to inform the U.S. Department of Defense initial capabilities documents (ICDs) for near-future satellite acquisition and development. By appreciating the history and technological challenges of employing lasers, rather than traditional radio frequency sources for satellite uplink and downlink signal carriers, this manuscript recommends ways for the U.S. Department of Defense to employ lasers to transmit and receive high bandwidth, and large-throughput data from moving platforms that need to retain low probabilities of detection, intercept, and exploit (e.g., carrier battle group transiting to a hostile area of operations, unmanned aerial vehicle collecting over adversary areas). The manuscript also intends to identify commercial sector early-adopter fields and those fields likely to adapt to laser employment for transmission and receipt.

The potentially imminent and existential threat from a nuclear electromagnetic pulse are arguably inflated, voiced to garner attention to the true issue, that today’s microelectronics are incredibly vulnerable to electromagnetic damage caused by sudden voltage spikes from the electromagnetic pollution. Additionally, a nuclear electromagnetic pulse does not need to be detonated in outer space to cause signification disruption to communications systems’ data and information flow across the celestial domain. High altitude electromagnetic pulse (HEMP) detonations do not need to occur in outer space to have wide ranging effects; in describing electromagnetic pulses, the high-altitude moniker is tied to any detonation above nineteen miles (thirty point-five kilometers). High altitude electromagnetic pulse detonations ranging from fifty to one hundred kilometers can project wave effects into outer space and affect spacecraft through both direct damage (contemporary views regarding electromagnetic pulse) and radiation-induced torques on the solar arrays, misaligning satellite antennas and sensors. If an actor – state or otherwise – wished to compete or contest another along the congested celestial lines of communications (CLOCs), it can be done at great distance from the affected entity by use of a high altitude electromagnetic pulse on the ‘far side’ of the orbit. Additionally, the historic maritime tactic of blockade has applicability in space; yesterday’s ships are today’s gamma ray damage to microelectronics. Furthermore, the employment of a nuclear weapon-delivered high-altitude electromagnetic pulse remains a treaty violation, for those who are a party to. However, greater jurisprudence study is lacking regarding this matter, and the accompanying concern of transboundary harm as it relates to territorial sovereignty. In summary, an actor can contest another’s use of the celestial lines of communications by detonating a nuclear weapon, at high-altitude but within the atmosphere (i.e., below one hundred kilometers), and within the lateral boundaries of their sovereign territory and associated territorial waters, and allow wave’s effects to radiate widely to interrupt operations and possibly inflict permanent damage, all without being in violation of treaty or customary law. This manuscript substantiates the prequel baseline for follow-on research on mitigation of the deleterious effects on communication system circuits in attempts to void the blockage on celestial lines of communications, and the sequel is briefly introduced with a short description of the state-of-the-art research.
