J2KJoin to Kill A different way to intercept ICBMs
THE THREAT MIRV + Decoys + Maneuvers
Decoys Why decoys are a major problem for BMD ?
Smart Decoys – RF+IR+Visible ? ? ? ? ? ? ? ? ? ? Very difficult to discriminate and hit the right target (WH). WHY is it so problematic?
Oooops… Very little time for discrimination, decisions, calculations, divert, hit WHY do we have such a short time?
Physics Assured discrimination range ~1 Km (Future sophisticated decoys) Relative velocity (ICBM) ~12 Km/sec Time from discrimination to hit – 80 mSec WHY is the relative velocity so high?
Mathematics Interceptor velocity = 6 Km/sec Relative Velocity = 12 Km/Sec WHY do we add velocities? Target velocity = 6 Km/sec +
Because… Interceptor flies head-on to the target WHY does it?
Because… That’s what everybody does! That’s the way we always did it! What’s the price of staying inside the box?
The price • Very complex interceptors • Huge NRE costs • High RE costs • Limited confidence • Entering the counter-counter game with deficiency and a time-lag of a decade • Limited answer for random-maneuvering RV’s (in space) • Any solution is sensitive to the enemy next-step Should we stay inside the box?
The J2K concept • Target velocity = 6 Km/sec • Interceptor velocity = 6 Km/sec • Relative Velocity = 12 Km/Sec • Time Budget = 80 mSec • Discrimination without time limits • Missile is simplified • Kill probability is much higher - + Breaking out of the box! 0 1,000,000 mSec
Joining the enemy warhead/s and decoys in a Formation Flight Discriminating and Destroying the Targets at ZERO RELATIVE SPEED J2K - THE PRINCIPLE
J2K – Think again… • Changing the rules of the game • Plenty of time for all tasks • Re-use of the system assets for multiple targets/decoys When your target is behind a concrete wall - You can break the wall Or you can outflank it
Detection & Recognition Defense Plan Launch J2K Interceptor towards CONUS. Separate KVs from booster Maneuvering to adjust position + velocity + time “Formation flight” J2K - THE RENDEZVOUS
During the formation flight Minutes instead of milliseconds. Examining the target/s and the decoys by the chosen sensor/s (electro-optical / LADAR / mmW radar) J2K - THE DISCRIMINATION
Small decoys - discrimination by shape Triple Decoys (IR, RADAR, Visible) - discrimination by dynamic behavior (tumbling) Quad Decoys (IR, RADAR, Visible, Dynamics) - If not discriminated – destroyed as targets J2K - THE DISCRIMINATION
I - Single-warhead scenarios - Closing the range to zero (touching the target) and exploding II - MRV/MIRV scenarios – Shooting high-speed bullets at the targets (this model discussed below) J2K – KILLING MECHANISM
The bullets are shot from a close range, in ideal conditions (no drag, no wind, no relative gravity fall) J2K – KILLING MECHANISM II – CONT. “Right between the eyes” • The bullet will severely damage the thermal shield of the target, which will cause its destruction while penetrating the atmosphere. • This option overcomes even the most sophisticated quad decoys (piercing the balloon)
J2K KV – Optional design Lateral nozzle 3 Reaction Wheels LADAR Gun DV nozzle Uncooled IR FPA + Lens 50 Bullets Magazine
First cut analysis results in the following major parameters for the Optional design: ~23cm diameter sphere ~28Kg ~13.5 Kg fuel 1 dV nozzle + 4 lateral nozzles 3 Reaction Wheels (satellites genre) for smooth and accurate rotation in all axes Uncooled FPA IR sensor LADAR/mmW Radar/Laser Range-Finder A “gun” with 50 high-speed bullets Miniaturized avionics with MEMS Inertial System Battery J2K KV – Optional Design
The J2K batteries can be deployed at US or friendly territories, from which they can cover possible ballistic trajectory attacking homeland USA (except some SLBM trajectories). Possible land based locations for different ranges are: Alaska + Aleutian Hawaii + Other pacific islands Great Britain (Shetland islands) Bermuda + Other Atlantic islands GROUND BASING
Ships patrolling in the preferred areas, far from home, to protect from ICBMs. A single dedicated ship can launch many interceptors. Fixed bases, such as oil rig type Medium-Range missiles launched from enemy submarines, can be intercepted by J2Ks launched from ships or the offshore oil rigs SEA BASING

A single KV can “clean” a sphere or a cylinder around the center of gravity of an incoming “cloud” (cluster) of targets and decoys, in the order of magnitude of 10 Km radius, by maneuvering in all 6 directions within the cloud. A single interceptor carrying 6 KVs, can protect a large area such as a large city. J2K – Coverage MIRV
J2K - Coverage Center of city is covered by 2-4 overlapping KVs Area covered by a single J2K KV Important Remark: This coverage of J2K is based on the worst-case assumption, that the engagement is accomplished just before entering the atmosphere. If the Interception occurs in earlier stages, the 10 Km radius of the single J2K KV coverage can be expanded to a much larger area Area covered by a single J2K Interceptor Carrying 6 KVs
J2K - Coverage Minuteman III Base 3 KVs J2K Defense (part of a single interceptor)
J2K - Coverage Minuteman III Base 6 KVs J2K Defense (a single interceptor) Most area is overlapped by 2-4 KVs
Overcomes both target maneuvers and decoys (of all types) One Interceptor can overcome many MIRVs and decoys Expected lower NRE and RE prices Lower technical risk - No need for technology break-through Can use any booster (e.g. GMD, KEI, SM, Arrow) Can be stationed on land or sea Less sensitive to the enemy next-step J2K - Summary
