responsive control surfaces and a more powerful rocket motor. IRIS-T SL In Germany, the PAC-3 MSE missile is expected to be supplemented by IRIS-T SLM as secondary missile for ground-based medium range air defense. It is based on the IRIS-T air-to-air missile equipped with an enlarged rocket motor, datalink, and jettisonable drag-reducing nose cone. Plug-and-fight In the BMC4I TOC, plug-and-fight flexibility lets MEADS exchange data with non-MEADS sensors and shooters. The same capability lets MEADS move with ground forces and interoperate with allied forces. Through interoperability features designed into the system, MEADS will dramatically improve combat effectiveness and situational awareness, reducing the possibility of friendly fire incidents. MEADS system elements can seamlessly integrate into each nation's, or NATO's, combat architecture as required. Units can be dispersed over a wide area. Command and control of launchers and missiles can be handed over to a neighboring battle management unit while the initial systems are moved, maintaining maneuver force protection. Plug-and-fight connectivity lets MEADS elements attach to and detach from the network at will, with no requirement to shut the system down. The MEADS plug-and-fight capability enables command and control over other air and missile defense system elements through open, non-proprietary standardized interfaces. MEADS implements a unique ability to work with secondary missile systems if selected, and to evolve as other capabilities are developed. Integration and test history In July 2010, the MEADS BMC4I demonstrated its interoperability with the NATO Air Command and Control System (ACCS) during tests using the Active Layer Theatre Ballistic Missile Defense (ALTBMD) Integration Test Bed being developed by NATO. The test was an early maturity demonstration for the MEADS BMC4I capability. In August 2010, the MEADS program completed an extensive series of Critical Design Review (CDR) events with a Summary CDR at MEADS International. Reviewers from Germany, Italy, the U.S., and the NATO Medium Extended Air Defense System Management Agency (NAMEADSMA) evaluated the MEADS design criteria in a comprehensive series of 47 reviews. In December 2010, the first MEADS launcher and Tactical Operations Center were displayed in ceremonies in Germany and Italy before initiating system integration tests at Pratica di Mare Air Force Base in Italy. In November 2011, it was announced that the MEADS Multifunction Fire Control Radar had been integrated with a MEADS TOC and launcher at Pratica di Mare Air Force Base. The objectives of the integration test series were to demonstrate that the MEADS
