Kinetic Energy Interceptor (KEI)

Details
The Kinetic Energy Interceptor (KEI), as currently envisioned, will provide land-based and sea-based defense against medium- and long-range ballistic missiles in all phases of flight.
KEI was originally conceived to provide boost-phase defense, or the ability to destroy enemy missiles just after they have been launched. In the boost phase, ballistic missiles are slow and vulnerable, their location is predictable, and countermeasures and decoys cannot be deployed. However, the Missile Defense Agency (MDA) recently announced that KEI will also attempt to destroy ballistic missiles in the midcourse and terminal phases.
The system initially will include (1) land-based interceptors mounted on mobile launchers, transportable by aircraft, and capable of deployment along the borders of threatening nations, and eventually will expand to (2) sea-based interceptors mounted on Navy destroyers and cruisers, possibly as part of the Aegis Ship-Based BMD. Once operational, KEI will be able to engage a medium- or long-range ballistic missile within the first five minutes of its flight.
Patriot-like mobile launchers will be used to transport the land-based interceptors. Each launcher will carry two interceptors housed in separate canisters, and will be transportable via a C-17 transport aircraft. It will take approximately three hours to set up each KEI battery of 10 missiles and 5 mobile launchers.
A command and control battle management and communications (C2BMC) component, consisting of six humvees, will integrate the KEI with the rest of the Ballistic Missile Defense System. Since KEI will not have its own radar or sensors, C2BMC will rely on systems deployed by other BMD programs such as the Aegis AN/SPY-1 radar system, the Space Tracking and Surveillance System (STSS), or the Sea-Based X-Band Radar (SBX).
Once a threat has been detected, KEI will launch its high-velocity interceptor missile (36 feet long and 36 inches wide), which will fly toward its target at two-and-a-half to three times the speed of the average tactical missile, thus making KEI the fastest of its kind. The first and second stages of the booster will burn together in 60 seconds, propelling the interceptor forward at a velocity of 6 kilometers per second.
During the third phase, the interceptor will adjust its trajectory and eject its “kill vehicle,” a small weapon that will incorporate elements from two other MDA defense projects: the Exoatmospheric Kill Vehicle (EKV), a device that is used to destroy enemy missiles outside the atmosphere; and the Standard Missile-3, a sea-based missile with a kinetic warhead. The kill vehicle will close in on its target, aim for the missile’s brilliant plume, and slam into the enemy warhead, completely destroying the threat.
Although the project is moving forward, KEI has recently become the subject of much controversy and doubt. Many strong proponents of missile defense believe that the project is too risky, might not work as planned, and diverts attention and resources from more promising programs such as Brilliant Pebbles and the Standard Missile-3 interceptor. For instance, Brilliant Pebbles was originally expected to receive $6 billion in development funding over the next five years, but will now receive only $843 million, with only $11 million for 2005. KEI, by contrast, will cost an estimated $22 billion over the next 10 years.
Others point out that MDA’s decision to shift KEI from a boost-phase to an all-encompassing defense system simply defies logic, since KEI will replace two brand new rockets that were recently developed at considerable expense. Another problem that many point out is the fact that the 36-foot long KEI interceptor missile will not fit on the Navy’s Aegis cruisers and destroyers, thus hampering the feasibility of relatively inexpensive sea-based deployment.
Nevertheless, KEI is fully funded and moving forward. In December 2003, MDA awarded an initial $4.5 billion contract to a Northrop Grumman-led team including Raytheon, Orbital Sciences, Aerojet, and ATK. The project is currently in the development and testing phase. Between 2003 and 2011, the team will produce 10 land-based interceptors and conduct 5 integrated flight tests. Deployment is scheduled for sometime between 2010 and 2012.

Northrop Grumman Awarded New Contracts for KEI
Reuters reports that the U.S. Missile Defense Agency plans to award Northrop Grumman two contracts totaling $2.5 billion for the Kinetic Energy Interceptor (KEI). The first contract, to be awarded this fall, will total $1.5 billion and will covers the costs of restructuring and stretching out the project. The second contract, to be awarded by September 30, 2007, will total $1 billion and will “add a capability to shoot down targets in the middle of their flight paths,” according to the Pentagon’s Program Director Carlton Brewer as quoted by Reuters. MDA plans to test the KEI’s booster capabilities in the in the fourth quarter of fiscal 2008 in a test that may decide whether to continue or kill the project.

Test of Kinetic Energy Interceptor Program
Northrop Grumman successfully completed the first of two FY 2006 tests of the Kinetic Energy Interceptor (KEI) battle management capability, known as the KEI Fire Control and Communications (KFC/C) system. The test was intended to verify that the system could meet the timelines and accuracy requirements necessary to engage and shoot down a target missile in its boost phase.
In the first test, which occurred on March 1, the team demonstrated that the KFC/C could forward sensor data received from multiple global satellite constellations to a deployed KEI battery. The next test will attempt to integrate the KEI sensors with external radar assets.
The KEI is a mobile ground-based missile defense system that is being designed to destroy enemy missiles during their boost and early-midcourse phases.

KEI Engine Test
The Kinetic Energy Interceptor (KEI) underwent the first in a series of static test firings of its second-stage rocket, on January 17. During the tests, the rocket motor burned successfully to completion, meeting performance and integrity expectations.
The KEI is the planned ground-based boost-phase interceptor component of the U.S. layered ballistic missile defense system. The significance of these engine tests are to determine if it is possible to develop an interceptor capable of extraordinarily fast acceleration, necessary to “catch up” with an enemy missile from a position on the ground.

KEI Missile Undergoes Wind-Tunnel Tests in Missouri
The Kinetic Energy Interceptor (KEI) recently underwent a series of high-speed wind-tunnel tests in St. Louis, Missouri, reports Jane’s Missiles & Rockets. The tests were intended to acquire data on the interceptor’s aerodynamics, high-frequency pressure, and acoustics, which will be used to select the proper nose shape for the KEI.
The KEI is the planned boost-phase interceptor component of the U.S. layered ballistic missile defense system.

Hackett: MDA Needs to Keep Eye on Goal
James T. Hackett of The Washington Times reports that U.S. senators have urged the Missile Defense Agency (MDA) to keep its eye on the goal: near-term deployment. In recent statements, Senators Ted Stevens (R-AK), Daniel Inouye (D-HI), and Jon Kyl (R-AZ) have emphasized that the MDA should spend its limited funds on deploying ground-based midcourse interceptors and ship-based missile defenses, rather than on duplicative or long-term projects such as the Kinetic Energy Interceptor (KEI). Many proponents of missile defense believe that the KEI project diverts attention and resources from more promising programs. The MDA has earmarked $5 billion for the KEI over the next four years.
Members of Congress are correct to urge the MDA to remain focused on the primary goal of deploying missile defenses in the near term.

Dinerman on Need to Divert KEI Funds to Space-Based Interceptors
Taylor Dinerman writes a fine piece for The Space Review on the need for missile defense budget cuts, if they are indeed to come, to be properly managed. If, as reported, the Missile Defense Agency must cut five billion dollars over the next six years, choices have to be made. Dinerman notes that “press reports indicate they have three choices: cut a little here and a little there, hoping to save all of their ongoing programs; cut the Airborne Laser (ABL); or cut the Kinetic Energy Interceptor (KEI). Sitting outside MDA, the answer is obvious, to wit, kill KEI.”
Dinerman goes on to recount the difficulties of the KEI design. While boost phase intercept is desirable, doing so with land-based interceptors is quite problematic, since they are very vulnerable to the problem of being in just the right place at just the right time. Dinerman then goes on to support perseverance with the promising sea-based Aegis defenses, as well as the Airborne Laser, but most importantly points to a more fundamental solution yet:
What is needed is to renew work on space-based boost-phase interceptors. The political obstacles are formidable indeed, but the case for Brilliant Pebbles or similar systems is as valid now as it was when the system was canceled by the late Les Aspin with the notorious quip, “I’m going to take the stars out of Star Wars.” Orbiting BPI weapons will not only give the US the capability to shoot down long-range missiles aimed at us but, and more importantly, it could allow the US to smother regional ballistic missile exchanges. Pick your own favorite nuclear missile nightmare scenario, and imagine how it would be changed if both sides found that their rockets were being knocked out of the sky. In a world full of nuclear proliferation, space-based BPI would be the ultimate diplomatic tool.

Garwin on Missile Defense
Richard Garwin writes in the November edition of the Scientific American on the need for missile defense efforts to be properly directed. He makes a number of good points about the ballistic missile threat, but his opposition to the means by which to meet that threat leaves questions unanswered. First, a summary of his main points:

KEI as a Multipurpose Weapon
Richard C. Barnard, editor of Sea Power, discusses in the most recent issue of the publication the future of the Kinetic Energy Interceptor as a “multipurpose” missile defense weapon—for use in not only the boost or ascent phase, but the midcourse phase as well. While the KEI was initially sold as a boost phase interceptor, it is now considering midcourse interception. Whereas boost phase interception would require extremely high speeds to “catch up” with a missile in a very short span of time, an interception in midcourse gives a longer span of time, allowing the same missile to proceed at a slower pace, thus also extending its range.
As a midcourse phase interceptor, the KEI could possibly be based aboard submarines or Aegis cruisers, though such possibilities would probably not be feasible until several years after the 2010 scheduled feasibility for the land based version. Barnard cites Terry Little, the KEI program director, as saying that a single battery of ten KEI interceptors stationed in Italy could, as a midcourse interceptor, protect all of Western Europe, and that another battery based in Norfolk Virginia could defend the entire East Coast from a ship-launched missile, launched between 300 and 1,500 kilometers offshore. Little admitted, however, that the land-based version would be incapable of destroying a missile from a larger country—such as Russia or China—in its boost phase, and that to do so would require a space based laser.

Hackett on MDA’s Priorities
Writing for the Washington Times, James T. Hackett notes the political challenges facing the new head of the Missile Defense Agency, General Trey Obering, who will preside over the initial deployment of America’s missile defense system this fall. Hackett also praises the Congress for trimming funding for the costly and problematic Kinetic Energy Interceptor (KEI).

Smith on the KEI
David J. Smith of the National Institute for Public Policy defends the Kinetic Energy Interceptor (KEI) as it is making its way through congressional committees for funding.
Smith’s piece in the Tucson Citizen seems to be a hometown push for the Tucson-based KEI program. Smith argues persuasively for the need for boost-phase defenses as part of a layered missile defense. But while the KEI is a boost-phase program, Smith does not address any of the recent criticisms, that a boost phase program based on land is inherently problematic, in no small part because of the need to be in the right place at the right time, namely very near to the launch site of any missile which it is meant to intercept. The ability of the KEI to be based in space or sea, however, would go far to eliminating many of its problems.
