P-3 Orion’s SMIP Program Keeps on Rolling

SMIP Activities

SMIP work is performed on all types, models and series of P-3 aircraft in the 164-aircraft U.S. Navy fleet, as well as P-3 aircraft supported through U.S. Navy-administered foreign military sales programs.

The US Navy formally launched a P-3 service life assessment program in 2000. That led to a full-scale fatigue test on a P-3C by 2002 – and the results shocked the Navy. Lockheed Martin’s assessment was based on a 1980s software algorithm, but testing showed that the problems were ahead of the algorithm, and new tools predicted very serious failures. That led to the creation of a Special Structural Inspection Kit, with wing undersides receiving extra attention.

SMIP work includes 2 types of activities.

The first type of SMIP activity involves those special structural inspections to ensure that corrosion from salt spray, or the stresses of repeated low-level swoops to near-sea level, haven’t created damage that might make the airframe unsafe before the next inspection. These services include:

• P-3 Special Structural Inspections (SSIs);
  
• Enhanced Special Structural Inspections (ESSIs);
  
• Fabrication and delivery of Special Structural Inspection Kits (SSI-Ks)

To ensure the aircraft remain safe, a Fatigue Life Management Program (FLMP) tracks and updates each P-3’s status every 6 months, and each plane’s flight hours and mission profiles are also monitored.

The inspections do find problems, as one would expect with aircraft this old. Next comes the actual work done. Sometimes, that just means regularly scheduled maintenance. Sometimes, the work involves installing new equipment, from upgraded electronics and radars to entirely new sets of wings. These services are referred to under SMIP as:

• Phased Depot Maintenance (PDM); and
  
• Modification/Installation Programs (MIPs).

The exact bundle of work varies to some extent from customer to customer, and MIPs will have contracts of their own attached to cover the cost of the equipment and any work “above and beyond.”

“Zone 5” – The Program and Process

The Zone 5 repairs are very extensive, requiring 21,000 man-hours of work, 6,000 holes drilled for rivets, and special equipment. Work includes replacement of 5 of the 9 lower wing planks, and the aft lower wing spar. When the Zone 5 repairs are complete, they provide an estimated 5,000 additional flight hours, or 8 – 10 years, to the aircraft’s airframe service lifespan. See NAVAIR’s “FRCSE Delivers First Red-Striped P-3 Back to the Fleet” for further details regarding the process.

Some countries like Norway have opted for an even more extensive plan, which involves a full re-winging, plus other replacements that include the horizontal stabilizer and engine nacelle components. Lockheed Martin has become the sole source for new P-3 wings as a matter of Pentagon policy, and a few outer wing kits were bought, but installation is the responsibility of other firms like L-3 Communications.

The main thrust, however, involved establishing rotatable wing pool, beginning with an order for 15 new wings. As P-3s come in and their old outer wings are removed and replaced, their old wings are refurbished and partially replaced, then returned to the pool.

The US Navy planned to ground 6 – 10 Orions a year, with all aircraft re-evaluated every 6 months. The re-winging effort and associated “Zone 5 modifications” is expected to take up to a year for each aircraft, and the US Navy expects to reach a steady state of 24 Zone 5 modifications (including re-wings) per year. That has accelerated somewhat due to fleet readiness issues, and as of September 2010, 45 P-3s were undergoing depot-level repairs.

Getting there required more than just spending money. The initial “Zone 5 groundings” in December 2007 kicked off a detailed value stream analysis of the entire P-3 industrial base. Two new plank and wing spar manufacturing vendors were certified, in order to make sure long-lead items would be available as needed. Another 3 depot facilities were brought under contract to conduct wing modifications and start work on the backlog of grounded aircraft. Existing contracts were restructured to reward higher depot throughput, and the Navy invested in machinery and production level management software for its own depot, in order to streamline P-3 repair operations.

SMIP Contracts and Related Announcements

The age of the fleet has even begun to involve re-winging and “Zone 5” work under a crash plan to, well, keep the P-3s from crashing. Because of their emergency nature and operational significance, those efforts are covered in a separate article: “US P-3 Recovery Plan Tries to Keep the Fleet in the Air.” Unless otherwise noted, US Naval Air Systems Command in Patuxent River, MD manages these contracts.

August 26/22: Aircrew Systems Dyncorp International won a $30.3 million modification, which exercises an option to extend services to provide continued organizational level aircraft maintenance and logistics support for aircrew systems and subsystems, search and rescue equipment, and support equipment for the P-3 Orion, C-130 Hercules, F/A-18 Hornet, E/A-18 Growler, AV-8B Harrier II, H-60 Seahawk, and E-2D Hawkeye aircraft in support of the Naval Air Warfare Center Weapons Division (NAWCWD) Naval Test Wing Pacific. Work will take place in California, Hawaii, Florida, New Mexico and Maryland. Estimated completion will be in April 2023.

December 22/21: Taiwan Lockheed Martin won a $21.7 million deal for P3-C aircraft mission system hardware, as well as obsolescence studies and technical support to maintain the P3-C mission systems for the government of Taiwan. The P-3C Orion land-based maritime patrol and anti-submarine warfare aircraft is operational in the airforces of ten countries. Work will take place in New York and Florida. Estimated completion will be by December 2026.

November 1/21: Maintenance Dyncorp International won a $60.5 million deal to provide organizational level aircraft maintenance and logistics support for aircrew systems and subsystems, search and rescue equipment, and support equipment for the P-3 Orion, C-130 Hercules, F/A-18 Hornet, E/A-18 Growler, AV-8B Harrier II, H-60 Seahawk, and E-2D Hawkeye aircraft in support of the Naval Air Warfare Center Weapons Division (NAWCWD) Naval Test Wing Pacific. Work will take place in California, Hawaii, Florida, Maryland and Arizona. Estimated completion is in September 2022.

January 29/21: Maritime Patrol and Reconnaissance Aircraft Program Lockheed Martin won a $11.4 million deal, which provides engineering and logistics services in support of the Maritime Patrol and Reconnaissance Aircraft program to monitor and manage fatigue and obsolescence issues and operational and/or technical problems arising from P-3 fleet usage for the Navy, Foreign Military Sales customers and other US government agencies. The P-3C Orion land-based maritime patrol and anti-submarine warfare aircraft was first operational in the US Navy in 1962. The P-3C first entered service in 1969 and has been continuously upgraded and updated with new avionics systems and mission equipment. More than 700 P-3 aircraft have been built by Lockheed Martin. The aircraft is operational in the airforces of ten countries. Work will take place in Marietta, Georgia and is expected to be finished in January 2026.

November 11/20: Training ESG Aerosystems won a $64.8 million deal to develop a curriculum and facilitate training for P-3 aircrew positions including copilots, patrol plane commander, instructor pilot, flight engineer, instructor flight engineer, and flight currency training in support of Naval Education and Training Security Assistance Field Activity’s applicable field units and other program offices and stakeholders. The P-3 Orion is a land-based maritime patrol and anti-submarine warfare aircraft. The contract includes a five-year ordering period with no options and is expected to be completed by November 2025. This effort is 100% funded by Federal Republic of Germany funds under the Foreign Military Sales program. In June 2020, Germany had put a halt to an ongoing midlife upgrade of its fleet of Lockheed Martin P?3C Orion maritime patrol aircraft (MPA) as it shifted to examining potential replacements. The legacy fleet of eight P-3C Orions were purchased secondhand from Royal Netherlands Navy (RNLN) stocks in 2005. The first unit entered German service in April 2006 following upgrades to P-3C CUP standard conducted by Lockheed Martin at its facility in Greenville, South Carolina, under a prior contract with the Dutch government. Work under the current contract will take place in Florida. Estimated completion will be in November 2025.

September 9/20: P-1 Not Replacing German P-3s Germany has decided to drop the Kawasaki P-1 maritime patrol aircraft from a list of contenders to replace its P-3 Orion. Berlin and Paris are shopping for a new aircraft that will enter service in 2025. This new aircraft will be a stopgap measure until 2035. However, Germany is worried that the P-1 might not be able to obtain a military type certification within five years. This will push the operational date beyond 2025.

June 18/20: Replacement in Germany According to Reuters, the naval air arm of the German Navy will look for a replacement of its P-3C. The service has decided against upgrading the aircraft in favor of buying a new platform, a confidential ministry document reviewed by Reuters showed. It has become expensive to maintain the Orion. The alternatives being evaluated are the C295, RAS 72 and P-8A.

January 23/20: Exercise Sea Dragon South Korea is participating in Exercise Sea Dragon for the first time, it dispatched a P-3C to Guam. South Korea had previously sent observers to the exercise. The Exercise Sea Dragon began on Monday and will last through the end January. Sea Dragon also involves Australia and New Zealand. It was designed to enhance the countries’ maritime patrol relationship and build anti-submarine warfare proficiency, according to the officials. It is the first time that South Korea partook in this exercise, a Navy official said, adding the Navy sent its P-3C patrol aircraft. The exercise comes amid concern that North Korea could launch an advanced type of submarine-launched ballistic missile. The communist country fired a Pukguksong-3 SLBM in October 2019 as the latest such test and pledged earlier this year to show off a “new strategic weapon” in the near future.

January 15/20: Japan To Middle East Japan has dispatched two P-3 maritime patrol aircraft to the Middle East from Naha Air Base on January 11. The aircraft will be used to patrol the Gulf of Aden, the northern Arabian Sea and the Gulf of Oman. They are deployed at Djibouti. Defense Minister Taro Kono said at the base on the day: “In addition to antipiracy operations, you will engage in new missions. Peace and stability in the Middle East are extremely important for the international community. Do your duty with courage and pride.” The MSDF aircraft were dispatched based on the “survey and research” provision stipulated in the Defense Ministry Establishment Law.

December 24/19: Argentina The US State Department approved a $78 million possible sale of equipment, parts, support and services for four P-3C Orion surveillance aircraft previously purchased by Argentina’s government from the United States. Argentina’s government had requested the possible sale to support and maintain its four P-3C aircraft, which it purchased from the US earlier this year. The request also included four turboprop engines for each airframe and four additional engines. The sale approved Wednesday will include communications, radar and optics equipment, as well as aircraft depot maintenance, spare parts and technical and logistical assistance.

October 22/19: Last Deployment Complete The US Navy completed the process of transitioning from P-3C Orion to the P-8A Poseidon earlier this month as the “Fighting Marlins” of Patrol Squadron FORTY returned to Naval Air Station Whidbey Island, Wash. The conclusion of a six-month rotational deployment on October 10, 2019, marked the final active duty deployment for the P-3C Orion, which served as the US Navy’s airborne anti-submarine warfare and maritime intelligence, surveillance, and reconnaissance (ISR) force for more than five decades. After post-deployment leave, the Fighting Marlins will begin the final of 12 active duty squadron transitions to the more modern and capable P-8A Poseidon. The US Navy will continue to operate its intelligence collection variant, the EP-3E, for several years along with reserve component operations before the official retirement of all P-3 variants.

August 5/15: The Navy’s P-3 Orion maintenance monitoring system, the Fatigue Life Management Program, was bolstered with a $32.3 million five-year contract with Lockheed Martin on Tuesday. Covering P-3 aircraft from the Navy and several other government agencies, the contract also provides engineering services for international operators, including the German Navy, which recently handed the company a contract to re-wing its eight P-3Cs. Similarly, Norway will also benefit from the contract, with the Scandinavian country also re-winging its Orions.

July 30/15: Following initial reports from early July, Germany has awarded an eight-year contract to Airbus Defence & Space and Lockheed Martin Overseas Services Corp. to re-wing the German Navy’s fleet of P-3C orion maritime patrol aircraft. The contract will cover eight P-3C aircraft, with Lockheed Martin manufacturing the new Mid-Life Upgrade kits on a production line opened in 2005 and Airbus responsible for integration and installation of the kits. Previous estimates put the value of a ten-aircraft contract at approximately $626 million. Norway has also invested in upgrading its Orions through a re-winging program. Germany previously requested aircraft mission computer, acoustic systems and simulator equipment for its Orion fleet, detailed in a DSCA request from April 2014.

Nov 15/13: FY 2014. L-3 Communications Integrated Systems, Waco, TX receives a $96.4 million indefinite-delivery/ indefinite-quantity contract modification, exercising an option for services in support of the P-3 (Orion, maritime patrol), EP-3 (Aries II, electronic eavesdropping), and NP-3 (testing plane) SMIP programs. This includes planned maintenance intervals, structural replacement and fabrication efforts pertaining to special structural inspection kits, center wing assemblies, Zone 5 kits, and outer wing installations and refurbishments.

Dec 23/11: Re-winging. US NAVAIR announces that artisans at Fleet Readiness Center Southeast (FRCSE) completed the installation of the 1st new set of wings on a P-3C Orion in November 2011.

“P-3 Orion Program Manager Clinton Batten said the artisans were still conducting Zone 5 repairs to the lower outer wing planks and the lower aft wing spar, but they were running into repair issues on the upper planks of the donor wings…. It is proving more cost effective to install new wings because of the many unknowns associated with refurbishing the old ones according to Cmdr. Stephen Tedford, PMA-290 P-3 Sustainment Integrated Product Team Lead.

An upper wing surface analysis performed in September 2009 determined that corrosion on the upper surface and not fatigue was the primary concern for the P-3 fleet.”

P-3s scheduled to remain in service the longest are getting the new wings, and FRCSE personnel have been providing feedback to Lockheed Martin re: how to assemble the wings being produced from 3-decade-old tooling. Apparently, the biggest obstacle has been aligning the new wings’ nacelles to hard points on the propellers. Sources: US NAVAIR, “FRCSE artisans rewing legacy P-3 Orion patrol aircraft to extend service life”.

Oct 20/11: FY 2012. L-3 Communications Integrated Systems – Waco Platform Integration Division in Waco, TX receives a $113 million indefinite-delivery/ indefinite-quantity contract modification, exercising an option for services in support of the P-3 (Orion, maritime patrol), EP-3 Aries II electronic surveillance, and NP-3 testing aircraft SMIP services. This includes planned maintenance intervals, structural replacement and fabrication efforts pertaining to special structural inspection kits, center wing assemblies, Zone 5 kits, and outer wing installations and refurbishments.

Work will be performed in Waco, TX, and is expected to be complete in October 2012. $5.6 million will expire at the end of the current fiscal year, on Sept 30/12 (N00019-11-D-0017).

May 25/11: FY 2011. L-3 Communications Integrated Systems – Waco Platform Integration Division in Waco, TX wins a $104 million indefinite-delivery/indefinite-quantity contract for services in support of P-3 (Orion, maritime patrol), EP-3 (Aries II, electronic eavesdropping), and NP-3 (testing plane) SMIP services.

April 18/11: Upgrades. Lockheed Martin receives a $23.8 million order for procurement of 76 acoustic processor and receiver tech refresh kits for the AN/USQ-78V acoustic subsystems aboard the P-3C Orion. Work will be performed in Manassas, VA, and is expected to be completed in February 2014. As one might guess, this is a P-3 MIP activity.

Oct 21/10: Stats. US NAVAIR says that it has 80 mission-ready P-3s of 147 in the fleet, and trending upward. It’s a vast improvement from the Fleet’s lowest point in 2009, when “only 49 aircraft were available for missions.” Source: US NAVAIR, “More P-3s Available for the Fleet”.

March 24/10: Upgrades. US NAVAIR discusses one aspect of the P-3 fleet non-structural efforts to stay ahead of obsolescence via MIP: radio replacement. According to P-3 Critical Obsolescence Program (COP) Team Lead Danny Hartwell, the existing Army/Navy Piloted ARC-161 analog radio was “costly and time consuming. We were required to replace the system organically…”

To hat end, the U.S. Navy recently began installation of an Organic Depot at Fleet Readiness Center South West (FRCSW) in San Diego, CA, to install AN/ARC-243 high-frequency radios in P-3s beginning in 2011. This is the same system that will be used for the Orion’s P-8A Poseidon; high-frequency radio provides instant over-the-horizon communications without the use of satellites, by bouncing signals off of the ionosphere.

Oct 17/09: Upgrades. Lockheed Martin announces a $17.5 million contract to upgrade existing AN/USQ-78V acoustic subsystems aboard the P-3C Orion. The contract includes upgrades and technical refreshes to software and Acoustic Receiver Tech Refresh hardware designed to comply with the Navy’s open architecture directives, replace obsolete components, provide increased processing capacity, and provide the framework for future aircraft upgrades. Work will be performed at Lockheed Martin’s Undersea Systems facility in Manassas, VA; Undersea Systems VP and GM Denise Saiki says that:

“This update provides an open Commercial Off-The-Shelf digital architecture using a modern digital receiver that is common across all maritime patrol and reconnaissance aircraft and helicopters… That helps drive down the total ownership cost of the platforms…”

Sept 17/09: Inspection kits. L-3 Communications Integrated Systems LP in Waco, TX receives a $39.7 million modification to a previously awarded indefinite-delivery/ indefinite-quantity multiple award P-3 SMIP contract (N00019-05-D-0013), for special structural inspection kit installation.
