Patrol and reconnaissance aircraft of the U.S. Navy and Customs and Border Protection
The US Navy has the largest fleet of carrier-based combat aircraft in the world. However, compared to the US Air Force, the Navy's tactical and strategic reconnaissance capabilities are aviation are far from what is desired, and American admirals are forced in this regard to rely more on other technical means and to establish an active exchange of operational information with other branches of the military and intelligence agencies.
In addition to the US Navy, the Coast Guard and Customs Service also operate aircraft designed for reconnaissance and surveillance, which are primarily used to interdict illegal immigration and the smuggling of narcotics into the country.
Northrop Grumman E-2C/D Hawkeye/Advanced Hawkeye carrier-based early warning and control aircraft
Northrop Grumman E-2C/D Hawkeye/Advanced Hawkeye airborne early warning (AEW) aircraft are a vital component in supporting the combat operations of US naval aviation. As of 2024, the US Navy operated 83 AEW aircraft, with an additional 25 E-2D variants on order. Approximately two dozen E-2C aircraft are in storage, but these aircraft, having reached the end of their service life and equipped with obsolete equipment, are unlikely to return to service. However, they can serve as a source of spare parts and unique components.

Meanwhile, carrier-based AWACS aircraft built in the 1980s, which have been modernized and overhauled, are still in service. Approximately 20 years ago, older Hawkeyes began to be equipped with the AN/APS-145 radar, and instead of the previous four-bladed propellers, aircraft built in the 1980s and 1990s received new eight-bladed NP2000 carbon fiber propellers reinforced with steel inserts. The engine control system was also modernized, equipped with digital controllers and sensors. This significantly reduced the response time to thrust changes and improved fuel efficiency. The modernized aircraft have improved takeoff and landing performance, increased range, and increased endurance. Many E-2C aircraft with significant remaining service life were brought up to the level of the Hawkeye 2000.
The most advanced American carrier-based AWACS aircraft to date is the E-2D Advanced Hawkeye. This aircraft, which first flew in 2007, incorporates cutting-edge technologies to improve crew conditions. In addition to new communications, navigation, display, and data processing equipment, the most notable innovation is the installation of the AN/APY-9 AESA radar, which is capable of detecting high-altitude aerial targets at a range of over 600 km and, thanks to its high energy potential, effectively monitors the flights of aircraft using low-radar technology.
This variant has a maximum takeoff weight of 26,082 kg. The empty weight is 18,234 kg. The length is 17,57 m, and the wingspan is 24,56 m. Two Allison/Rolls-Royce T56-A-427A turboprop engines, each producing 5100 hp, provide a maximum speed of 650 km/h. Cruising speed is 474 km/h. The flying radar picket can conduct patrols for six hours. The ferry range is 2,700 km. The crew consists of two pilots and three radar operators.
In addition to the surveillance radar, E-2C/D aircraft are equipped with electronic reconnaissance equipment capable of receiving high-frequency signals, classifying them, and determining their coordinates. In the past, carrier-based Hawkeyes were used in reconnaissance missions using only passive receiving equipment, without activating the radar.

Two aircraft belonging to these squadrons have also been spotted at Lakehurst Air Force Base in New Jersey, where several different types of catapults used for takeoff training and a ground laboratory complex for testing and debugging various onboard electronic systems are built. In 2019, a modified E-2D Advanced Hawkeye was launched from an electromagnetic catapult here.
Lockheed P-3 LRT Orion and Lockheed P-3 AEW Orion patrol and reconnaissance aircraft operated by the U.S. Customs and Border Protection
Customs and Border Protection is the largest law enforcement agency within the U.S. Department of Homeland Security. Among other responsibilities, this federal agency is tasked with interdicting drug trafficking. weapons and other illegally imported goods, as well as preventing illegal migration.
In the 1980s, the flow of illegal drugs into the United States increased dramatically. In addition to traditional delivery methods, smugglers began to make extensive use of light aircraft crossing the border at low altitude. Ground-based radars, which were primarily used for air traffic control, were clearly insufficient for effectively detecting low-altitude targets, and the American ground-based radar network in the southern United States had been significantly reduced in the early 1970s. In this case, AWACS aircraft could have monitored the airspace from Mexico and the Gulf of Mexico, where the main drug flow originated. However, the constant use of heavy AWACS aircraft for this purpose was too expensive, and the command used the relatively economical E-2 Hawkeye. fleet allocated extremely reluctantly.
As new Hawkeye variants were introduced into carrier-based air wings, older E-2Bs and E-2Cs were reassigned to shore-based reserve squadrons. These aircraft were used by the Coast Guard and Customs Service. However, the aircraft's age and inadequate electronic equipment took their toll. In several cases, crews were forced to abort patrols due to avionics failure or problems with worn-out engines.
The Hawkeye, designed for carrier deployment, had insufficient endurance when deployed from a shore airfield. The situation was exacerbated by the fact that older AWACS aircraft typically lacked in-flight refueling equipment, and the Border Customs Service did not have its own tanker aircraft.
To reduce operating costs, the Navy transferred several heavily battered E-2Cs to the Border Patrol in the late 1980s. These aircraft were crewed by retired U.S. Navy pilots and operators, and maintenance was performed by former Navy technicians. However, after a Hawkeye assigned to the Border Patrol Service crashed on August 24, 1990, due to a technical malfunction during a patrol flight, killing its crew, all carrier-based AWACS aircraft were returned to the Navy.
To close the gap that had opened in American airspace on the Gulf of Mexico side, there was an urgent need to create an inexpensive patrol and reconnaissance aircraft capable of hovering in the air for 8-10 hours.
In the mid-1980s, the US Navy began replacing its obsolete, but still robust, Lockheed P-3A/B Orion patrol aircraft with improved P-3Cs, which featured sophisticated avionics and weapons systems by the standards of the time. To detect aerial targets, four P-3As, designated P-3CS after conversion, were equipped with used Hughes AN/APG-63 pulse-Doppler radars, removed from F-15A/B fighters that had been upgraded with the more advanced AN/APG-70 radars.
Thus, the P-3CS radar picket aircraft was purely a budget ersatz variant, assembled from whatever was at hand. Naturally, the capabilities of the converted Orions could not compare with the radars and data-sharing systems of fully-fledged AWACS aircraft. Consequently, the Coast Guard and Border Patrol, despite the aircraft's lower cost, were not entirely satisfied with them. However, the US federal agencies responsible for border protection and coastal water control did not abandon the use of patrol aircraft with relatively low-performance radars. As the converted P-3As with AN/APG-63 radars were decommissioned, their place was taken by P-3 LRT (Long Range Tracker) aircraft, converted from refurbished P-3Bs stored at Davis-Monthan, Arizona.
Google Earth satellite image of Lockheed P-3 Orion aircraft at Davis-Monthan Air Force Base.
Based on operational experience with the P-3C, these aircraft, in addition to the AN/APG-63V radar with a detection range of up to 150 km, received side-looking optronic systems capable of detecting boats or light aircraft at ranges of several dozen kilometers. Furthermore, Orions operated by the Customs and Border Protection retained their submarine detection equipment, as drug traffickers have begun using small submarines to infiltrate the United States.
This patrol modification, based on the P-3B, was designated the P-3 LRT and remains in service today. The P-3 LRT has an eight-person crew (pilot, co-pilot, flight engineer, radar and optronic systems operators). Operational support at the forward airfield is provided by a three-person ground crew. Based on recent satellite imagery, three P-3 LRT aircraft remain in service.

Customs and Border Protection's Aviation and Marine Division patrol aircraft are based at airfields in Corpus Christi, Texas; Cecil Field; Point Mugu, California; and Jacksonville, Florida. The distinctive CBP insignia of these aircraft is a zigzag blue stripe painted forward on the fuselage.
Overall, the P-3 LRT patrol aircraft satisfied US border officials, but the AN/APG-63V radar did not provide 360-degree coverage of the airspace. This problem was partially solved by carefully planning the flight path, with the aircraft making figure-eight and donut-shaped turns along the most likely routes of intruders. However, the detection range of the fighter-based radar, although quite compact and relatively low-powered, left much to be desired. But then Lockheed came to the aid of federal agents fighting the smuggling of mind-expanding substances, developing the P-3 AEW airborne early warning and control aircraft on its own initiative.
The first aircraft built had the same radar as the E-2C—the AN/APS-125, with an antenna in a rotating dish-shaped radome. This radar could detect a smuggler's Cessna against the sea at a range of over 250 km. Initially, the P-3 AEW was offered for export as a cheaper alternative to the E-3A Sentry. However, no foreign buyers were found, and the sole customer was the U.S. Customs and Border Protection.
The onboard equipment included communications equipment capable of operating not only on Coast Guard and Border Patrol frequencies but also capable of direct targeting of interceptors. Later-production aircraft received new AN/APS-139 and AN/APS-145 radars, better suited for detecting low-speed air and surface targets. The first P-3 AEWs were painted a striking red and white. The last such aircraft was decommissioned approximately in 2018.

To extend their service life, Orion-based AWACS aircraft are overhauled and modernized under the Mid-Life Upgrade program. P-3 AEW aircraft undergo a complete airframe inspection and replacement of components affected by fatigue wear and corrosion. This extends the aircraft's service life by another 20-25 years. New navigation and instrumentation, as well as communications and display systems similar to those used on the E-2D Advanced Hawkeye, are installed. In the future, the P-3 AEW may be equipped with the latest AN/APY-9 radars, surpassing the capabilities of the carrier-based E-2D. The four-engine P-3 AEW is a much larger aircraft, capable of significantly longer patrol missions. The Orion has a larger interior, allowing for the installation of additional reconnaissance and search equipment.

Ten years ago, 14 P-3 LRT and P-3 AEW aircraft served in border aviation units. Currently, their number has been reduced to nine. To replenish the P-3 AEW and P-3 LRT fleet, P-3B/C aircraft from the Davis-Monthan "boneyard" in Arizona, where more than 180 are stored, could be used.
General Atomics MQ-9B Reaper UAVs operated by the U.S. Customs and Border Protection
The U.S. Department of Homeland Security became interested in the medium-class UAV in 2003 and received its first MQ-9B in the fall of 2005. As of 2012, Customs and Border Protection operated nine MQ-9Bs. Two were based at Grand Forks Air Force Base in North Dakota, four at Fort Huachuca in Arizona, and one at Naval Air Station Corpus Christi, Texas.

Currently, unarmed troops are used to protect the sea and land borders. Drones The MQ-9B SeaGuardian has an endurance of over 18 hours. Drone The MQ-9B SeaGuardian UAV can patrol for eight hours at a range of 2200 km from its airfield. The MQ-9B SeaGuardian UAV is equipped with Raytheon MTS-B optronic infrared sensors and a Leonardo Seaspray 7500E V2 AESA synthetic aperture radar, which can detect surface targets, including ships, submarine periscopes, and personnel.
The basic patrol and anti-submarine aircraft Lockheed P-3C Orion and special reconnaissance modifications created on its basis
For a long time, the primary American shore-based patrol and anti-submarine aircraft was the turboprop Lockheed P-3C Orion. This aircraft is an evolutionary development of the previous modification, the P-3B, which replaced the P-3A in operational squadrons, which traces its lineage back to the Lockheed L-188 Electra airliner, which first took to the air in 1957. In addition to fighting submarines, the modified P-3C could carry out mine laying, over-the-horizon target designation and warning for surface ships, conduct reconnaissance, and strike land and sea targets with guided missiles. rockets.
The P-3C aircraft has a maximum takeoff weight of 61,235 kg. Length is 35,61 m. Wingspan is 30,38 m. Four Allison T56-A-14 turboprop engines, each producing 4910 hp, enable it to reach a speed of 760 km/h at an altitude of 4500 m. Cruising speed at an altitude of 7600 m is 607 km/h. Patrol speed at an altitude of 460 m is 382 km/h. Ferry range is 8950 km. Flight endurance is up to 17 hours. A combat load of up to 9100 kg can be accommodated on external components and in internal compartments. There is space on board for 11 people.
The aircraft remained in serial production until 1990. Lockheed built 650 units of all variants. Another 107 Orions were built under license by Japan's Kawasaki. Currently, virtually all P-3Cs in US naval aviation have been replaced by the new-generation Boeing P-8A Poseidon.

NP-3D aircraft are equipped with a Billboard side-looking radar and optronic sensors. In the past, these aircraft monitored missile tests. During the American presence in Afghanistan, two NP-3Ds conducted detailed radar mapping of the country's territory.
In 2025, the 1st Marine Reconnaissance Squadron, based at Naval Air Station Whidbey Island, Washington, operated several Lockheed EP-3E Aries II electronic intelligence aircraft. One such aircraft also operated with the 20th Test and Development Squadron at Naval Air Station Patuxent River, Maryland.

The EP-3E aircraft were developed in the 1990s by converting basic P-3C patrol aircraft, which had logged little flight time. The naval aviation received a total of 12 of these aircraft. The customer received the last aircraft of this type in 1997.
Google Earth satellite image of a Lockheed EP-3E Aries II aircraft at Patuxent River Air Force Base. The image was taken in June 2022.
The electronic reconnaissance aircraft, based on the P-3C, differs externally from the standard Orion in its large longitudinal antenna located in the upper rear fuselage and a radome antenna behind the tail, installed in place of the magnetic anomaly sensor. Of the P-3C's search equipment, the reconnaissance aircraft retains only the AN/APS-115 radar, but adds electronic reconnaissance systems and electromagnetic and infrared jamming stations. The EP-3E is similar in basic specifications to the base aircraft, but the crew and electronic reconnaissance operators on board can exceed 20.
The Navy's EP-3E aircraft were used very intensively, and their presence was noted in various regions of the planet. Until recently, they were active in the Middle East, regularly scanning assets. Defense Russia, Cuba, China and North Korea intercepted radio communications and monitored the naval exercises.
An incident involving an EP-3E on April 1, 2001, caused a stir. On that day, a crew at a Chinese radar station located in the southeastern part of Hainan Island detected an aerial target flying at an altitude of 6700 meters and a speed of approximately 370 km/h along the edge of China's territorial waters. Two J-8D interceptors scrambled from Lingshui Air Base, located on the island's east coast, toward the unidentified target. After closing in on the target, the Chinese pilots identified it as an American EP-3E ARIES II electronic reconnaissance aircraft.
Having detected the interceptors nearby, the Americans descended to 2400 m and reduced their speed to a minimum. Since the stall speed of the J-8D jet is much higher than that of a turboprop, the EP-3E commander intended this to force the Chinese to climb and abandon the pursuit. However, the plan failed: during the third flyby of the intruder, during a close maneuver, one of the interceptors collided with an American reconnaissance aircraft and crashed into the South China Sea. His pilot was missing in action and later presumed dead.
The EP-3E aircraft sustained no fatal damage in the collision and was able to continue its flight. It was forced to land on Hainan Island under threat of gunfire. The American crew failed to completely destroy the classified materials on board. The Chinese military obtained cryptographic and intelligence equipment, encryption keys, call signs, radio frequency lists, and information regarding the operation of radar stations in China, Vietnam, North Korea, and Russia.
A US State Department official was forced to apologize for the incident and pay monetary compensation to the widow of the deceased pilot. Following this, the Chinese government abandoned the trial of the American military personnel, and the 24-member crew was released. The electronic reconnaissance aircraft was disassembled and returned to the US on July 3, 2001, aboard a Russian An-124 heavy transport aircraft. The EP-3E, gutted by Chinese specialists, was then decommissioned.
According to available information, all EP-3Es in service as of early 2025 are to be decommissioned and transferred to the Davis-Monthan storage facility.

Following the decommissioning of the Lockheed EP-3E Aries II, the duties of conducting electronic reconnaissance have been assigned to the crews of Boeing P-8A Poseidon aircraft and Northrop Grumman MQ-4C Triton UAVs.

Boeing P-8A Poseidon basic anti-submarine and reconnaissance aircraft
The turboprop Orion was an excellent aircraft for its time, and these aircraft are still actively used by twelve nations. However, by the beginning of the 21st century, American admirals realized that naval aviation needed a new, modern aircraft that, in addition to improving anti-submarine capabilities, would also serve as an effective patrol and reconnaissance platform, carry a variety of weapons, and interact with long-range UAVs.
The competition to replace the Lockheed P-3C Orion was announced in 2000. Boeing won the bid in 2004, offering an aircraft based on the Boeing 737-800 airliner and designated the P-8A Poseidon after its introduction into service. The initial contract was for 108 aircraft, but the US Navy subsequently ordered additional aircraft, and as of October 2025, 136 were in service, with three more expected. Including foreign purchases, 185 aircraft had been built as of May 2025. Poseidons are produced at Boeing's facility in Renton, Washington. Major subcontractors include Raytheon, Northrop Grumman, Spirit AeroSystems, GE Aviation Systems, Marshall Aerospace and Defense Group, CFM International, BAE Systems, and Marotta.

For military use, a number of modifications were made to the basic design. To compensate for the loads associated with more frequent low-altitude flights than the base aircraft, the P-8A was equipped with a more robust wing from the Boeing 737-900. Because the Poseidon's onboard equipment consumes significantly more power than a civilian aircraft, each CFM International CFM56 engine on the P-8 is equipped with a 180 kW electric generator, replacing the 90 kW generator. This necessitated a redesign of the nacelles and their wing mounts. The P-8A uses canted wingtips, similar to those on the Boeing 767-400ER, instead of the composite wingtips found on the civilian Boeing 737NG.
The aircraft is equipped with mechanical anti-icing systems. Changes have been made to the flight control and warning system software, allowing for a greater bank angle, a more responsive autothrottle, and the elimination of audible warnings during low-altitude flights. The airframe's strength has been increased, and a bomb bay for torpedoes and other cargo has been added.
With a length of 39,47 m and a wingspan of 37,64 m, the P-8A has a maximum takeoff weight of 85,820 kg. Two CFM56-7B27A turbofan engines have a maximum takeoff thrust of 121 kN each. Maximum flight speed is 907 km/h. Cruising speed is 815 km/h. Combat radius is 2,225 km. Ferry range is 8,300 km. Service ceiling is 12,500 m.
A payload of up to 9,000 kg is accommodated on six external hardpoints and in an internal compartment. Mark 54 anti-submarine torpedoes, equipped with a glide module, can be used from an altitude of over 9,000 m. The armament suite also includes AGM-84 Harpoon, AGM-84H/K SLAM-ER, AGM-88G AARGM-ER, AGM-158C LRASM guided missiles, Sting Ray torpedoes, naval mines, and depth charges. Unlike the turboprop Orion, the turbofan Poseidon is not equipped with a magnetic anomaly sensor, but carries much more sophisticated search and reconnaissance equipment, which is operated by seven operators. The flight crew consists of two people. Seven operators operate the onboard equipment.
The first production P-8A was delivered to the US Navy on March 4, 2012, and after being flown to Naval Air Station Jacksonville, Florida, it was assigned to Training Squadron 30. Currently, six operational, one training, and one reserve squadron equipped with Poseidons are based in Jacksonville as part of the 11th Patrol and Reconnaissance Wing on the US East (Atlantic) Coast.

Northrop Grumman MQ-4C Triton UAV
Almost simultaneously with the order for the next-generation patrol and reconnaissance aircraft, the US Navy announced a competition for a long-range unmanned aerial vehicle (UAV) that could replace the aging Orion aircraft for routine patrol missions. The winning bid was a UAV based on the Northrop Grumman RQ-4 Global Hawk. Compared to the original high-altitude reconnaissance drone, the naval version features a reinforced airframe and wing, an anti-icing system, and lightning protection. This allows the aircraft to fly below cloud cover for better visibility of ships and other objects on the sea surface. Onboard equipment enables the UAV to track and classify ships, determine their speed, and determine their coordinates.
The MQ-4C Triton is being considered as a complement to the Boeing P-8A Poseidon maritime patrol aircraft and is designed to provide intelligence and reconnaissance missions over vast ocean and coastal regions with real-time data transmission, continuous maritime surveillance, and search and rescue operations.
The primary means of detecting maritime targets during high-altitude flights is the X-band active electronically scanned synthetic aperture radar (AESA) with 360-degree coverage. The radar can capture high-definition radar images and then use its onboard computing system to automatically recognize and classify targets without operator intervention.
Unlike the Global Hawk, the Triton, thanks to its more robust design and lightning protection, is capable of rapid descent and low-altitude flight. In this case, the primary reconnaissance instrument is the Raytheon MTS-B multispectral optronic system, combined with a laser rangefinder/target designator. The MQ-4C UAV is also equipped with modular receiver equipment, similar in capabilities to that used on the Lockheed EP-3E Aries II electronic reconnaissance aircraft. This allows it to passively detect, classify, and geolocate weak radar signals and transmit the information to other users.
The MQ-4C can also act as a network relay and data center. It can receive and transmit messages from across the theater of operations, from aircraft, ships, and ground stations located beyond line-of-sight, and combine this information to create a common "picture" of the battlespace. This significantly improves interoperability and situational awareness, and provides an alternative to satellite communications systems.
The MQ-4C Triton UAV has a gross takeoff weight of 14 kg. It is 14,5 m long and has a wingspan of 39,9 m. Its Rolls-Royce AE 3007 turbofan engine, producing up to 39,66 kN of thrust, provides a maximum speed of 575 km/h (630 mph). Its range is up to 15 km (200 mi). Its endurance is 30 hours. Its service ceiling is 17 m (000 ft).
The MQ-4C Triton made its maiden flight on May 22, 2013, taking off from Palmdale Airfield in California. Assembly of prototype and production aircraft took place at Northrop Grumman's Palmdale facility.
