Reliability calculations and cost estimated are discussed, and normalized evaluation of jamming effectiveness is recommended. Budgets are also found for key satellite subsystems: payload, structures, thermal, power, TT&C, attitude control, and propellant. Spacecraft key design budgets are calculated next revealing the requirement for a large spacecraft (~7333kg, 7.8m X 61.1m 2) and large launch vehicle (Atlas V class). These key design features are used to establish a link-budget that reveals mission margin. Astrodynamics reveals that a low-earth orbiting altitudes of 100-400 kilometers produces jamming effects on the target emitter for 4.8-10.2 minutes respectively producing jammer energy received by the targeted radar of -23.9 to -102.9 decibel-watts respectively. The design requires elements of mechanical engineering, electrical engineering, and aerospace/astronautical engineering at least. Using these key thresholds, space mission analysis and design (SMAD) is articulated in detail for the first time in the literature, revealing rough-order-of-magnitude budgets for system design. It is revealed that only a single satellite is required for effective jamming with transmitter power of 2-9 kilowatts, transmission gain of at least 25 decibels, while maintaining a bandwidth less than 80 megahertz and assumed losses less than 30 decibels (where 10-20 decibels is typical). Electromagnetic propagation equations are simulated and iterated to reveal key threshold values of key design parameters. Next key design parameters are iterated in physics-based simulations to drive subsequent design efforts. Inspired by aerial combat in the Balkans (Serbia and Kosovo) in 1999 with no known support suppressing enemy air defenses (SEAD) from space, this article proposes such by first introducing the reader to basic electromagnetic principles in order to evaluate the SEAD radar jamming mission from space.
