Capability enhancement
Marshall is proud to work with global OEMs and fleet operators to extend the mission capability and longevity of their aircraft, while self-certifying our own work.
Whether we’re replacing the centre wing box on a C-130J Super Hercules or increasing the operating range of Boeing’s P-8A Poseidon patrol aircraft, capability enhancement is at the core of what Marshall does.
Adaptable Role-fit Capability (ARC)
Marshall’s Adaptable Role-fit Capability (ARC) product family includes a range of platform-agnostic systems designed to rapidly enhance an aircraft’s capability within hours, enabling fleet operators to flexibly and efficiently reposition their aircraft for different types of mission - from cargo transport to medical evacuation and even intelligence, surveillance and reconnaissance (ISR).
Radar
Marshall ARC Radar is a modular sensor suite that allows operators of tactical transport aircraft to quickly and temporarily outfit an aircraft for intelligence, surveillance and reconnaissance (ISR) missions.
As the first of several products within the Marshall Adaptable Role-fit Capability (ARC) family, ARC Radar is a palletised solution with no permanent integration and no modifications required, utilising only existing aircraft power outlets.
The system’s potential applications are remarkably broad, ranging from military ISR land, sea or air missions to applied civilian operations such as search and rescue, humanitarian support, and disaster relief. Despite being fitted temporarily, the Osprey 30 radar suite maintains full performance during operation.

Aeromedical evacuation system (AMES)
Marshall ARC AMES enables fleet operators to outfit aircraft for tactical and strategic medical evacuation missions on demand, giving medium- and high-dependency patients the optimum chance of survival during air transport.
The palletised system can be rapidly installed and removed, requiring no modifications to the aircraft and utilising the existing aircraft power supply.
AMES can be configured to specific operational needs, while its modular design allows multiple modules to be connected to support additional patients.
Multiplatform cargo winch
Marshall’s roll-on, roll-off multiplatform cargo winch supports the loading of heavy objects - particularly in remote locations where ground support equipment is unavailable.
The system can be installed without any modifications, and makes use of existing electrical outlets for power, meaning it can easily be transferred as needed between multiple aircraft within a single fleet.
Modernisation programmes
The Lockheed Martin C-130 Hercules remains the global tactical airlift platform of choice, having been in continuous production for longer than any other military aircraft in history. The airframe’s unmatched longevity is one of its hallmarks, with some aircraft built over 60 years ago still in operation today.
While operating a fleet of legacy C-130 aircraft is an extremely viable and cost-effective way to maintain tactical capability, maximising the lifespan of this legendary aircraft will require regular upgrades to ensure continued airworthiness and compliance with evolving aerospace regulations.
Marshall has an exceptional track record in delivering multi-year upgrade programmes designed to ensure that any C-130 aircraft can continue to support tactical operations around the world for many decades to come. We are also able to self-certify our own work, eliminating potential points of failure while ensuring we deliver a high-quality end-to-end solution for our customers.
Structural modernisation
Having replaced almost every major structural component on the C-130 without OEM involvement from Lockheed Martin, Marshall occupies a leading position in the non-standard repair and replacement market. We have even developed bespoke jacking and trestling instructions and equipment to allow significant structural items to be refurbished and replaced efficiently and to the highest standards.
Case Study - fueslage stretch programme
Over the course of three years, Marshall performed an unprecedented fuselage stretch programme for the UK’s Royal Air Force (RAF). By adding two new fuselage sections to 29 C-130 aircraft, we were able to extend their total length by 15 feet and increase cargo compartment volume by roughly a third.
The OEM-supplied parts comprised a 100 inch plug for the front section of the aircraft, and an 80 inch section between the wing and the para troop doors. In addition to fitting the new sections into place, Marshall fully adapted the aircraft’s systems and wiring.
These aircraft flew for years and completed many vital missions, ferrying supplies and undertaking medevac sorties, among other duties.
Centre wing box replacement
The centre wing box is a fatigue-life item that will require replacement to ensure the continued airworthiness of the aircraft - no major C-130 structural component attracts such a high operational load.
Marshall is the world’s only maintenance, repair and overhaul organisation to have performed centre wing box replacement on both C-130K and C-130J aircraft - an exceptionally complex modification that can only be undertaken with dedicated facilities, tooling and knowhow.
Once the existing centre wing unit is removed, we install a zero life centre wing box kit - manufactured by Lockheed Martin - that delivers significant durability enhancements and provides service life extension for the centre wing box by up to three times longer than the original units.
Centre wing box replacement on Lockheed Martin C-130 aircraft
Working in collaboration with Lockheed Martin, Marshall performs centre wing box replacement in a specially refurbished state-of-the-art hangar, harnessing our extensive C-130 deep maintenance and modification expertise, along with the use of lean processes, to remove and reinstall the new centre wing box as quickly and efficiently as possible.

Avionics modernisation
Marshall has decades of expertise in avionics modernisation, overseeing comprehensive programmes from start to finish including design, installation, commissioning, testing and self-certifying.
We can perform avionics studies on any C-130 fleet, creating bespoke modernisation packages to address obsolescence, provide operational capability enhancements and ensure compliance with international aviation regulations. Our experienced test pilots work alongside a dedicated engineering team to evaluate the suitability and usability of all upgrades.
Case Study – Royal Netherlands Air Force (RNLAF) cockpit upgrade and cabin safety improvement
As part of one of Marshall’s most extensive and complex engineering projects to date, we undertook a comprehensive avionics upgrade for four legacy RNLAF aircraft, comprising a cockpit upgrade programme (CUP) and a cabin safety improvement programme (CSIMP).

Lightweight armour
Thanks to an exclusive agreement with QinetiQ, Marshall is the first company to certify and deliver the latest generation of lightweight armour (LAST Armor® LWA) for the C-130 Hercules, giving operators around the world confidence that their crews are protected against small arms fire in hostile environments.
The armour is manufactured from high tenacity polyethylene, making it extremely robust and remarkably light. It can be quickly and easily installed during scheduled maintenance or as a standalone activity, thus ensuring optimum aircraft mission availability.
“It was an easy decision to work together with Marshall Aerospace to certify and install the LAST Armor LWA onto our fleet of C-130Js. The level of protection provides a greater probability of mission success in harsh environments or potential conflicts and has promoted confidence in our aircrew.”

Operating range extension
Marshall has decades of expertise in developing and providing solutions that extend the operating range of aircraft - whether through the production of auxiliary fuel tanks or the installation probes for aerial refuelling.
Fuel tanks
For over four decades, Marshall has produced auxiliary fuel tanks that have been retrofitted to 10 commercial and military aircraft types across five major OEMs including Airbus, Bombardier and Boeing. We offer a safe, reliable and certified solution needed to meet range-extension requirements, today and in the future.
We have been working extensively with Boeing since 1997, initially providing auxiliary fuel tanks for commercial airliner variants such as the 747-400ER and 777-220LR Worldliner. Since 2009, we have been Boeing’s exclusive supplier of auxiliary fuel tanks for the globally successful P-8 Poseidon maritime patrol aircraft, end customers for which include the United Kingdom, United states, Australia, India, New Zealand and Norway.
The auxiliary fuel tanks extend the flight range of the aircraft and allow for additional time on station. Marshall supplies the tanks in ship-sets of six, along with a number of components. With over 1,100 tanks produced to date, we have achieved an uninterrupted 100% on-time delivery record and 100% quality performance for over a decade.
The certified dual-wall aluminium honeycomb structure we use for our P-8 tanks is a cost-effective solution that maximises strength and reliability while also providing very competitive weight-to-fuel volume performance. Our tank designs offer a 15% increase in fuel volume compared to conventional bladder solutions, while also requiring less frequent maintenance.
We are constantly embedding continuous improvement into our processes and using of new materials such as composite solutions to expand the capabilities of our fuel tanks and systems.
Aerial refuelling probes
Marshall has extensive experience providing fixed-mast receiver probes for aerial refuelling on a variety of civil and military aircraft types, including the Lockheed L1011 Tristar, Embraer 145, and Lockheed Martin C-130K Mk1/Mk3 and C-130J. These are simple, reliable additions to the aircraft with minimal maintenance requirements.
As the sole supplier of aerial refuelling probes for the C-130J, we carry out design, analysis and manufacturing in house, delivering completed probes – along with in-fuselage centre-wing connection kits – to Lockheed Martin’s final assembly line in Marietta. These probes are already installed on the Italian, Indian and Australian C-130J fleets, and can be supported on all non-US operated C-130J aircraft.
