Missile Systems
Modern missile systems range from short-range tactical weapons to intercontinental ballistic missiles. They employ diverse guidance strategies - inertial, GPS, radar, infrared, and command guidance - and are countered by layered missile defense architectures protecting against threats at every flight phase.

Missile Trajectory Comparison
Ballistic Missile
Powered boost phase, then free-flight through space (midcourse), followed by re-entry and terminal guidance. High speed, high altitude arc.
Cruise Missile
Sustained powered flight at low altitude using terrain-following or sea-skimming. Harder to detect by radar but slower than ballistic.
Key Facts
- Ballistic missiles follow a parabolic free-flight trajectory after an initial powered boost phase
- Cruise missiles fly at low altitude using sustained propulsion (turbofan/turbojet) with terrain-following guidance
- ICBM ranges exceed 5,500 km; they can carry multiple independently targetable re-entry vehicles (MIRVs)
- Terminal guidance systems include active radar homing, semi-active laser, infrared imaging, and GPS/INS
- Missile defense operates in three phases: boost (launch), midcourse (space), and terminal (re-entry)
- Hit-to-kill interceptors destroy targets through kinetic energy impact rather than explosive warheads
- Hypersonic missiles (Mach 5+) challenge existing defense systems with speed and maneuverability
- Anti-ship cruise missiles like the Harpoon use sea-skimming profiles to avoid radar detection

Stealth Technology
Stealth technology reduces the detectability of aircraft and vehicles by minimizing their radar cross-section (RCS), infrared signature, visual signature, and acoustic emissions. Through careful shaping, radar-absorbent materials, and design integration, stealth platforms achieve a decisive tactical advantage.
Electronic Warfare
Electronic Warfare (EW) encompasses the use of the electromagnetic spectrum to sense, protect, and attack. It includes electronic attack (jamming), electronic protection (counter-countermeasures), and electronic support (signals intelligence), forming a critical dimension of modern warfare.
