50 anni di P-3 Orion
Quest'anno oltre al B-52 che raggiunge i 60 anni di età, c'è il Lockheed P-3 Orion che ne fa 50..lui però ha già il sostituto sulla rampa di lancio, il P-8 Poseidon.

Dall'archivio di "Flight International" .....Origins .....
In August 1957, the U.S. Navy called for replacement proposals for the aging twin piston engined Lockheed P2V Neptune (later redesignated P-2) and Martin P5M Marlin (later redesignated P-5) with a more advanced aircraft to conduct maritime patrol and antisubmarine warfare.
Modifying an existing aircraft was expected to save on cost and allow rapid introduction into the fleet.
Lockheed suggested a military version of their L-188 Electra, which was still in development and had yet to fly.
In April 1958 Lockheed won the competition and was awarded an initial research and development contract in May.
The prototype YP3V-1/YP-3A, Bureau Number (BuNo) 148276 was modified from the third Electra airframe c/n 1003.
The first flight of the aircraft's aerodynamic prototype, originally designated YP3V-1, was on 19 August 1958.
While based on the same design philosophy as the Lockheed L-188 Electra, the aircraft was structurally different.
The aircraft had 7 feet (2.1 m) less fuselage forward of the wings with an opening bomb bay, and a more pointed nose radome, distinctive tail "stinger", wing hardpoints, and other internal, external, and airframe production technique enhancements.
The Orion has four Allison T56 turboprops which give it a top speed of 411 knots (761 km/h) .....

Video della dimostrazione in volo di un esemplare neozelandese (nel 2003)
I turboprop T56 seppur in una sottoversione diversa sono praticamente gli stessi che avevano i vecchi C-130 (non i "J" per intenderci)

Fonte .....The P-3C Orion differs little in outward appearance from its predecessors the P-3A and -3B, but its interior is markedly different from those of the earlier Orions in that it houses more than 300 pieces of avionics equipment, some 200 of which were not incorporated in the -A and -B models.

L-3 delivers refurbished P-3C Orion back to US Navy .....
By: Dave Majumdar (Washington DC - 06 Nov. 2012)
Source: Flight International
L-3 has delivered its first refurbished Lockheed Martin P-3C Orion maritime patrol aircraft back to the US Navy under the sustainment, modification and installation programme (SMIP).
L-3 preforms SMIP work on all variants of the Orion airframe, 147 of which are still in service, for the USN, the company says. That includes P-3 outer wing refurbishment, P-3 outer wing installation, special structural inspection kits, phased maintenance inspections and modification/installation programs.
The company says it will only get better over time in refurbishing the ageing four-engined turboprop.
"We are committed to continuous improvement, and we know that accelerating the turnaround time in such a dramatic way reduces the cost of sustainment and increases the operational availability of the aircraft to the warfighter," says Nick Farah, executive vice president of L-3 Platform Systems.
L-3 was first awarded the SMIP contract in 201, the indefinite-delivery, indefinite-quantity programme is a follow-on to a similar contract awarded to L-3 in 2005.
