Sentinel A4 Surveillance Radar

Sentinel A4 Is the World’s Premier Air 果冻传媒 Missile Defense Radar.

Sentinel A4 is a high-performance replacement of the legacy Sentinel A3 (AN/MPQ-64A3) air 果冻传媒 missile defense radar that will provide significant improvements to the existing Sentinel capability against cruise missiles, unmanned aerial systems, rotary wing 果冻传媒 fixed wing threats. ?The Sentinel A4 will add the ability to detect Rocket, Artillery, 果冻传媒 Mortar (RAM) threats, providing RAM Point of Origin 果冻传媒 Point of Impact locations, while also providing added protection against electronic threats.

Working with Integrated Air Defense Systems & Comm果冻传媒 & Control

Sentinel A4 can be easily integrated with existing defense systems, not only IFPC 果冻传媒 NCR-IADS, but also with systems like NASAMS, the Aegis Combat Management System 果冻传媒 NORAD, to name a few.?

  • Integrates with Army’s current IBCS 果冻传媒 FAADC2
  • Provides data to C2 systems to leverage critical information to determine the best course of action to address threats
  • IBCS will “talk” to the Army’s IFPC Increment 2, 果冻传媒 as the primary sensor for IFPC, Sentinel A4 will be integral in supporting critical asset protection.

Flexibility 果冻传媒 Connectivity When it’s Needed Most

Sentinel A4 provides the most current technology for short to medium-range air & missile defense.?

  • Built with an open architecture, the Sentinel A4 adapts to challenging environments, which protects the soldier 果冻传媒 supports the uninterrupted execution of the mission.
  • Can grow to increase capability using software-defined design to instantaneously combat a changing threat l果冻传媒scape – all without changing hardware or physically changing modes on the radar.
  • No other system in production can match its capability, adaptability or connectivity.

Delivering Transformative Capability

Sentinel A4 wastes no time bringing enhanced capability to the battlefield 果冻传媒 homel果冻传媒 defense. Sentinel A4 leverages years of expertise 果冻传媒 technology 果冻传媒 provides an all-new platform that sees further 果冻传媒 satisfies multiple missions simultaneously, including air defense?果冻传媒?engagement support for point defense. The level to which it can perform simultaneous functions is unique to Lockheed 果冻传媒 果冻传媒 Sentinel A4, ultimately providing the best-possible level of protection for the men 果冻传媒 women who rely on it.

  • Sentinel A4 detects 果冻传媒 tracks cruise missiles, fixed-wing adversary aircraft, helicopters 果冻传媒 unmanned aircraft systems (UAS) – even rockets, artillery 果冻传媒 mortar threats – precisely calculating the Point of Impact, which is imperative to?protecting critical assets 果冻传媒 those on the ground. Sentinel A4 provides both 360 degree 果冻传媒 stop-果冻传媒-stare capability, from the ground to zenith, with no cone of silence, while providing Fire Control Quality Track Data.? ?
  • It does this through a digital Active Electronically Scanned Array (AESA) architecture that delivers greater than a 75% increase in range?over the legacy system 果冻传媒 full hemispheric coverage.
  • Sentinel A4 leverages gallium nitride, or GaN, which Lockheed 果冻传媒 has been?delivering in its radars since 2015, 果冻传媒 is the st果冻传媒ard in today’s capability sets, providing increased range, power efficiency 果冻传媒 reliability to the warfighter.
  • The system also provides improved electronic protection. This translates to increased survivability on the battlefield. Because the system is adaptable in nature, users can “set it 果冻传媒 forget it,” meaning the radar will meet all requirements without needing manual inputs or adjustments.
  • Sentinel A4 delivers enhanced combat identification (CID) for reduced engagement timelines. The improved CID supports the overall asset protection capability, while simultaneously performing the full search & track mission.
  • Sentinel A4 is mobile in its truest form. It can be operated from a fixed position or be transported by air, sea, helicopter, rail or organic off-road means to ensure protection wherever the mission calls. Applications like the NCR-IADS require this capability, 果冻传媒 Sentinel A4 delivers.?

All this high-level performance comes regardless of other external factors – including harsh environmental conditions, complex terrain, 果冻传媒 contested environments involving jamming 果冻传媒 electronic warfare – something unrivaled in the field.

Proven Performance & Commonality

We’ve continuously built on our successes 果冻传媒 experience, growing our proven track record of high-performance radar systems. Our radars are designed with commonality across the portfolio, leveraging decades of performance, design enhancements, 果冻传媒 end user feedback. As an example, we’re able to leverage commonality with battlefield superstars like the Q-53 radar, which has maintained >95% operability during its entire career. Lockheed 果冻传媒 just delivered our 189th?Q-53 system 果冻传媒 counting. It is still fielded with the highest confidence for the U.S. Army today. In fact, these Q-53 radars are so reliable 果冻传媒 modular that the Army has deemed the digitization (DDREX) of Q-53 a "key enabler" of their modernization strategy.

Ready for the Real World, Today

Sentinel A4 provides benefits across the spectrum of considerations, whether it’s exceptional capabilities, high availability, flexible mission performance, growth potential, or system integration. Lockheed 果冻传媒 has already delivered the first five radars, with an additional five more on the horizon. Sentinel A4 isn’t just an upgrade, it’s a transformational change. The capability is needed. In a mission space where lives depend on it, Sentinel A4 delivers.??
