The Boeing P-8 Poseidon (formerly the Multimission Maritime Aircraft or MMA) is a military aircraft developed for the United States Navy (USN). The aircraft has been developed by Boeing Defense, Space & Security, modified from the 737-800ERX.
The P-8 conducts anti-submarine warfare (ASW), anti-surface warfare (ASUW), and shipping interdiction, along with an electronic signals intelligence (ELINT) role. This involves carrying torpedoes, depth charges, SLAM-ER missiles, Harpoon anti-ship missiles, and other weapons. It is able to drop and monitor sonobuoys. It is designed to operate in conjunction with the Northrop Grumman MQ-4C Triton Broad Area Maritime Surveillance unmanned aerial vehicle. The aircraft has been ordered by the Indian Navy as the P-8I Neptune, and theRoyal Australian Air Force. The Royal Air Force also intends to order the P-8. Source wikiwand.com
In June 2004, the US Navy announced the selection of the Boeing multimission maritime aircraft, 737 MMA, and awarded a contract to Boeing for the system development and demonstration phase of the programme for the US Navy’s next-generation maritime surveillance aircraft. The aircraft was given the designation P-8A in March 2005.
It is expected that up to 117 P-8A MMA aircraft are to be purchased by the navy to replace the fleet of 196 P-3C Orion maritime patrol aircraft which are approaching the end of their operational lives. The initial operational capability (IOC) of P-8A was achieved in November 2013.

The US Navy has operated the land-based P-3 Orion maritime patrol aircraft for anti-submarine warfare and anti-shipping, as well as for overland surveillance, reconnaissance, mine-laying, drug interdiction logistic, threat simulation crew training and search and rescue missions.
Although developed to counter the Soviet submarine threat, the maritime patrol force, greatly reduced in size since the end of the Cold War, finds itself in great demand in the littoral warfare environment of the early 21st century. The current front-line version is the P-3C which equips 12 active and seven reserve patrol squadrons the P-3C entered service in Baseline form in 1969 and has been upgraded since through various update configurations. Modifications to their equipment has sharpened their capabilities. The Lockheed P-3 Orion is currently in service with 15 countries.

The US Navy started a two-year requirement study in 1997 for the replacement of the Navy’s P-3C Orion, and the Defense Acquisition Board initiated a number of concept studies between 2000 and 2002.
An assessment of the proposals by the USN led to contracts being placed with Boeing and Lockheed Martin in 2002 for the component advanced development phase.
The Australian Government announced the acquisition of eight P-8A Poseidon maritime surveillance aircraft for the Royal Australian Air Force (RAAF) in February 2014. The $4bn contract also includes an option for four additional aircraft. The new RAAF aircraft performed a four-hour flight in the vicinity of the naval air station in April 2015. Delivery of the first P-8A will take place in 2017 and all eight aircraft will achieve full operational capability in 2021.
Proposal details from Boeing and Lockheed Martin
Boeing submitted proposals based on the 737-700 aircraft and Lockheed Martin’s proposal was based on the Orion 21, a new version of the P3. The industrial team led by Boeing includes Raytheon, Northrop Grumman, Smiths Industries, CFM International, GE Aviation and Spirit AeroSystems.
Boeing built a 737 BBJ2 (Boeing Business Jet) technology demonstrator aircraft to demonstrate the aircraft and on-board systems capabilities. Two functional mission system consoles were installed on the aircraft.
In December 2003, the aircraft completed a tour of US Navy bases and naval air stations in Brunswick, Maine, Jacksonville, Florida, Norfolk, Virginia, Kaneohe, Hawaii and Whidbey Island, Washington.
The demonstrations included maximum power take-off and climb to 12,500m (41,000ft), manual reversion manoeuvres with no hydraulics, maximum rate of descent at more than 3,050m/min (10,000ft/min), tactical manoeuvres at an altitude of 200ft, simulated single-engine manoeuvres and performance landing achieving a stopping distance of less than 610m (2,000ft).
The selection of the Boeing 737 MMA was announced in July 2004 with the contract award covering the manufacture of five trial aircraft during the next eight years. One aircraft each has been allocated for airworthiness tests, static tests and fatigue tests, and two aircraft for testing the mission systems.
Boeing P-8A Poseidon test aircraft T-1 conducts a test flight
The preliminary design review (PDR) was successfully completed in November 2005. The critical design review was completed in July 2007. Boeing began production of the first of five test aircraft in December 2007. The first flight of the P-8A test aircraft T1 was completed in April 2009. The first mission systems test flight of the T2 was successfully completed in June 2010. The test aircraft T3 completed its first flight test in July 2010.
Full-scale static testing on the airframe of the first ground-test vehicle S1 was completed in January 2011. The fatigue tests on S2, the second ground-test vehicle, began in late 2011. The first P-8A production aircraft completed its maiden flight in July 2011.
Boeing 737-based design
The aircraft design is based on the proven fuselage of the 737-800 and the wings of the 737-900. The P-8A aircraft has increased gross weight capability compared with the 737-800.
In June 2005, Boeing announced that the design of the P-8A’s wingtips has been changed from the blended winglet to a backswept wingtip. In June 2006, Stork Aerospace of the Netherlands was awarded the contract for manufacturing the backswept (or raked) wingtips.
The internal weapons bay is installed beneath the forward section of the fuselage. The 737-900-style wings are built with hardpoints for carrying air-to-surface missiles.
The 737 MMA is assembled at the Boeing production facility in Renton, Washington, US. The 737’s fuselage and tail sections are built by Spirit AeroSystems in Wichita, Kansas, before being transferred to Renton, where all the unique 737 MMA aircraft structural features are incorporated in sequence during fabrication and assembly.
The quality and performance acceptance flight testing of the aircraft was conducted from Renton Field and final installations and checkout of the mission system and special flight test instrumentation was conducted at the Boeing Field. The aircraft then ferried to naval air station at Patuxent River, Maryland, for flight test.
P-8A Poseidon cockpit and flight management systems
The flight management system and the stores management system were developed by Smiths Aerospace. The Smiths Aerospace flight management system is based on an integrated open architecture and will be compatible with the installation of future upgrade systems.
Parvus DuraVIS 4300 and 3006 display systems
The Parvus DuraVIS 4300 and 3006 display systems are used inside the Boeing P-8A Poseidon aircraft. The P-8A’s flight display systems were tested to the same shock (15 gsawtooth) and random vibration profiles (0.022 g²/10 Hz to 0.0026 g²/2,000 Hz) that would be required if they were moved to harsher environments, ensuring the highest standard of ruggedized durability. This robust system design philosophy has led to follow-on projects with single- and multi-core processors onboard the AC-130, CP-140, and P-3. Source mil-embedded.com
The cabin is fitted with up to seven operator consoles.
In March 2008, Boeing selected L-3 Communications Wescam to supply the MX-20HD digital electro-optical and infrared (EO/IR) multispectral sensor turrets for the P-8A Poseidon. MX-20HD is gyro-stabilised and can have up to seven sensors, including infrared, CCDTV, image intensifier, laser rangefinder and laser illuminator.

Is the Navy’s P-8A Poseidon jet evolving into a multi-sensor strategic reconnaissance platform?: Here
The U.S. Navy’s P-8A Poseidon — a long-range maritime-patrol and submarine-hunting version of the Boeing 737-800 single-aisle passenger jet — may be evolving into a multi-sensor strategic reconnaissance aircraft that eventually could rival other surveillance planes like the Navy EP-3 and the Air Force RC-135.
The SAR provides multiple-resolution strip map and spot SAR operation, and allows high-resolution for target identification, battle damage assessment and weapons targeting.
Periscope detection uses high-scan speeds, high-pulse repetition frequency and high-resolution mode with advanced sea clutter rejection.

AN/ALQ-213 EW Management Unit
The Electronic Warfare Management System (EWMS) ALQ-213 product family is the core system of Terma’s integrated Electronic Warfare (EW) systems solutions. As a subsystem and aircraft independent system, the ALQ-213 integrates individual subsystems into one combined system. The pilot has one single interface to all self-protection subsystems which results in increased survivability and reduced stress on the pilot in critical situations.
In collaboration with a large number of end users and aircraft manufacturers, the performance and capabilities of Terma’s EWMS have continuously been expanded over the past two decades. Today, the product represents the most common and mature Electronic Warfare management system in the market.
One Coherent System Solution
The ALQ-213 management system manages all subsystems automatically and displays alerts, status, etc. as one coherent system instead of a number of individual subsystems.
Terma’s management system is unique in the sense that, on one hand, it creates an integrated systems solution, but on the other hand, it does not need to be tightly integrated into the aircraft’s main control software. This means low integration costs as well as increased flexibility for the users.
Commonality across Platforms
The uniqueness of the ALQ-213 family of controllers is that the same product can be used across a mixed fleet of aircraft (fighters, helicopters, and fixed wing transport aircraft) because the products have been developed for generic solutions rather than dedicated platforms.
Freedom of Choice
The ALQ-213 allows for integration of any EW subsystem (Radar-, Missile-, Laser Warning, Direct InfraRed CounterMeasures systems, Jammers, Decoys, and Dispensers) enabling us to deliver the solution that best meet operational requirements and budget.
A Total EW Package
As a mature product, the ALQ-213 product family comes with all necessary tools supporting all phases of the flight from planning, recording, training, and analysis for continuous optimization of the operational performance. Source terma.com
