MH-60R

Overview

The MH-60R “Romeo” is the most capable and mature Anti-Submarine (ASW)/Anti-Surface Warfare (ASuW) multi-mission helicopter available in the world today. Together with its sibling, the MH-60S “Sierra,” the SEAHAWK variants have flown more than 650,000 hours across a 500+ aircraft fleet. The MH-60R is deployed globally with the U.S. Navy fleet and a growing number of allied international navies.

The journey from the start of MH-60R flight testing through the first deployment, in 2009, of 11 MH-60R helicopters aboard the USS Stennis, represents 1,900 flight hours, the equivalent of 500 labor years, and a considerable financial commitment by Lockheed Martin.

The MH-60R, manufactured by Sikorsky Aircraft Corp, and equipped with advanced mission systems and sensors by Lockheed Martin Mission Systems and Training (MST), is capable of detecting and prosecuting modern submarines in littoral and open ocean scenarios. In addition, it is capable of conducting stand-alone or joint anti-surface warfare missions with other Romeo or MH-60S “Sierra” aircraft. Secondary missions include electronic support measures, search and rescue, vertical replenishment, and medical evacuation.

The advanced mission sensor suite developed and integrated by Lockheed Martin includes:

  • Multi-mode radar  (including Inverse Synthetic Aperture Radar)
  • Airborne Low Frequency Dipping Sonar (ALFS) subsystem and sonobuoys
  • Electronic Support Measures with an integrated helo threat warning capability
  • Forward Looking Infrared Electro-Optical device
  • Integrated self defense
  • A weapons suite including torpedoes and anti-ship missiles

Lockheed Martin MST also produces the Common Cockpit™ avionics, fielded on both the MH-60R and MH-60S. The 400th Common Cockpit will be installed on the first Royal Australian Navy MH-60R. In 2012, the Common Cockpit exceeded 600,000 flight hours across an operational fleet of 360 aircraft. The digital, all-glass cockpit features four large, flat-panel, multi-function, night-vision-compatible, color displays. The suite processes and manages communications and sensor data streaming into MH-60 multi-mission helicopters, presenting to the crew of three actionable information that significantly reduces workload while increasing situational awareness.

The U.S. Navy is committed to a long-term preplanned product improvement program, also known as P3I, to keep the MH-60R current throughout its life. Recent upgrades have included vital software and mission management systems in the Situational Awareness Technology Insertion (SATI) package as well as design upgrades to the Identification Friend-or-Foe Interrogator Subsystem. Combined with the aircraft’s Automatic Radar Periscope Detection and Discrimination system, the MH-60R’s range of detection will expand — enhancing situational awareness and advanced threat detection — while interference with civil air traffic control systems will diminish.

The MH-60R Electronic Surveillance Measures (ESM) system, which provides aircrew with valuable threat-warning capabilities, has benefited from the installation and maintenance of an ESM autoloader, and the development of Mission Data Loads, which comprise a database of possible threats within a specific region of operations.

Smaller elements are included as well, including the integration of a new multi-function radio called the ARC210 Gen 5 (which sister-aircraft MH-60S will also receive), crucial spare assemblies and integration of other core technologies. The Gen 5 radio will provide MH-60R aircrew with flexible and secure communication.
