Long-term aircraft storage has, within two decades, become an industrial segment in its own right within the aerospace value chain. Driven by accelerated fleet renewal, recurring overcapacity cycles and the mass conversion of passenger aircraft into freighters (P2F), operators are looking for sites capable of accommodating several hundred aircraft under conditions that slow down their ageing as much as possible. Yet these conditions are not found anywhere on the planet. They require a very specific climatic equation — extreme dryness, abundant sunshine, no atmospheric salinity, no freeze-thaw cycles — that only a few regions of the world can offer. Southern Algeria is one of these exceptional zones, on a par with the Mojave Desert in California or the Tucson basin in Arizona. And the Saharan arc, which spans nearly four million square kilometres, adds to these natural assets a decisive variable that the American sites will never be able to offer European and African fleets: proximity.
Why climate is the first criterion of aircraft storage
Before tackling the geographic comparison, it is worth recalling what "storing" an aircraft actually means. A modern long-haul jet — whether a twinjet of the A330 family or a four-engine machine of the previous generation — is an assembly of more than four million parts whose materials react differently to their environment. Aluminium alloy structures, carbon composite assemblies, elastomer seals, polyurethane paints, electrical harnesses, avionics computers and hydraulic fluids do not share the same sensitivity to humidity, ultraviolet light, thermal swings and chemical contaminants.
Atmospheric corrosion is the primary enemy. Any water molecule present in ambient air condenses on metallic surfaces cooled overnight, triggering within a few months micro-pitting that later requires expensive panel removals. The presence of chloride ions — typical of marine atmospheres — accelerates this phenomenon by a factor of ten. Photodegradation of polymers and paints is the second front: ultraviolet light breaks the molecular chains of organic materials, hardens seals, weakens acrylic windows and dulls coatings. Finally, daily and seasonal thermal cycles mechanically fatigue assemblies, particularly when they include a crossing of the freezing point — the freeze-thaw cycle that bursts water infiltrations trapped within structures.
An ideal storage site therefore combines five characteristics: an average annual relative humidity below 30 %, near-zero rainfall, complete absence of saline aerosols, no crossing of 0 °C, and a stable bearing ground. These conditions all stem from the same underlying phenomenon: the presence of a continental high-altitude desert climate, far from any maritime coast.
Mojave as global benchmark: forty years of history
The Mojave Air & Space Port, open to civilian storage since the 1970s, has imposed itself as the global benchmark for long-term parking. Located at around 850 metres of altitude in the desert of the same name, the site benefits from an average annual relative humidity of 25 %, around 3 500 hours of sunshine per year, rainfall below 150 mm and more than three hundred cloudless days. Pinal Airpark, near Tucson, displays a very similar profile: 700 metres of altitude, 30 % average humidity, around 300 mm of rainfall concentrated in a few summer monsoon episodes.
Roswell in New Mexico and Victorville in California complete this quartet of North American desert airports. Together, they permanently host more than a thousand commercial aircraft, ranging from regional twinjets to the latest wide-bodies. Forty years of accumulated experience have made it possible to build a true technical doctrine for long-term storage — fluid revisit intervals, engine ignition cycles, intake protection methods, airframe inspection schedules — which today serves as a global standard and is widely echoed in ICAO Doc 9760 (Airworthiness Manual) and in the EASA Part-M on continuing airworthiness management.
The American ecosystem nevertheless suffers from a structural limitation: it was designed for North American fleets. Ferrying a European or African aircraft to Mojave represents a transatlantic positioning flight of eight to ten hours, empty, consuming between fifty and eighty tonnes of jet fuel and triggering the carbon offset obligations applicable under the CORSIA regime. For a Mediterranean operator, this transatlantic logistics is a major source of friction.
The Algerian Sahara: four million square kilometres of exceptional industrial climate
The Algerian Sahara covers around 84 % of the national territory, which represents nearly two million square kilometres within Algerian space alone. It is a geographical platform without equivalent in the world for its climatic homogeneity: almost everywhere within it, one finds a hyperarid climate with very low humidity, annual rainfall below 50 mm, sunshine ranging from 3 500 to 4 000 hours per year, and more than three hundred and fifty rain-free days.
The plateaux of southern Algeria combine an average altitude between 400 and 1 500 metres, rocky soils naturally compacted by aeolian erosion, and a distance from the Mediterranean coast that is consistently above 600 kilometres. This dual characteristic — continental altitude and maritime distance — virtually eliminates saline aerosols, one of the most valuable parameters for the preservation of aluminium structures. By comparison, a coastal site, even under a dry climate, sees its atmospheric corrosion rate multiplied by five to ten relative to an equivalent continental site.
The geological stability of the Hoggar and the great ergs also provides a rarely mentioned advantage: the absence of significant seismic activity across most of southern Algeria. Long-term storage zones thus benefit from a calm bearing ground, generating no vibration stress on parked landing gears.
Detailed comparative table
| Parameter | Southern Algeria (reference) | Mojave (CA) | Pinal Airpark (AZ) | Roswell (NM) |
|---|---|---|---|---|
| Average relative humidity | 15 to 25 % | ≈ 25 % | ≈ 30 % | ≈ 35 % |
| Annual rainfall | 20 to 50 mm | ≈ 150 mm | ≈ 300 mm | ≈ 380 mm |
| Annual sunshine | 3 500 to 4 000 h | ≈ 3 500 h | ≈ 3 800 h | ≈ 3 200 h |
| Freeze-thaw days | ≈ 0 (lowland zones) | 10 to 25 | 5 to 15 | 30 to 60 |
| Atmospheric salinity | Near zero (continental) | Near zero | Near zero | Near zero |
| Average altitude | 400 to 1 500 m | ≈ 850 m | ≈ 700 m | ≈ 1 100 m |
| Significant sand winds | Yes (hangar-managed) | Rare | Rare | Possible |
| Ferry distance from Europe | 2 to 3 h | 10 to 11 h | 10 h | 10 to 11 h |
Reading this table leaves little room for ambiguity: on the physico-chemical parameters that matter most for aircraft preservation, southern Algeria equals or surpasses the American reference sites. It loses ground on only one parameter — the presence of sand winds — which is addressed by technical solutions long tested in the oil and aerospace industries of the Arabian Gulf.
The decisive difference: distance from Europe
This is probably the most underestimated factor of the comparison. Ferrying a European aircraft to southern Algeria represents a direct flight of two to three hours, against ten to eleven hours to reach Mojave. The economic translation of that gap is massive: a transatlantic ferry consumes around sixty-five tonnes of jet fuel per long-haul airframe, emitting roughly two hundred tonnes of carbon dioxide. The same aircraft positioned to the Sahara consumes between ten and fifteen tonnes — four times less.
The calculation becomes even more telling when indirect costs are added: transatlantic overflight charges, customs duties and temporary admission procedures with the FAA, ETOPS constraints that lengthen the routing, and the immobilisation of the ferry crew. An internal estimate, based on average costs published by IATA, places the total gap between 350 000 and 500 000 US dollars per long-haul aircraft ferried across the North Atlantic, compared with a Mediterranean-Sahara positioning. For an operator storing twenty aircraft, that is between seven and ten million dollars saved on entry logistics alone.
To this is added a reputational dimension increasingly integrated by airline finance departments: reducing the carbon emissions of repositioning flights for end-of-life or pre-conversion aircraft. The European sustainability regulation (CSRD) now requires European carriers to publish a detailed carbon assessment of their operations, including ferry flights. Storing at two hours of flight rather than ten is no longer just a matter of cost; it is a matter of regulatory compliance and corporate image.
African position: a crossroads between Europe, West Africa and East Africa
Southern Algeria is not only close to Europe; it is also central to the African continent. Geography places the major Saharan plateaux roughly equidistant from the main African hubs: around three hours of flight from Dakar, two and a half from Abidjan, three from Lagos, four from Nairobi, three and a half from Cairo. No other African site combines this geographical centrality with an equivalent industrial climate. West African airports suffer from average humidity above 75 %, East African ones from heavy rainfall, and South African coastal sites from strong atmospheric salinity.
For African carriers, whose fleets are modernising rapidly and which must simultaneously manage fleet entries and exits, having a regional storage and transition centre is a strategic stake. Transcontinental ferries to North America are becoming economically and ecologically difficult to justify. The Algerian Sahara appears as the natural successor of that ageing logistics chain.
The specific challenges of the Sahara and how they are addressed
Recognising the strengths of the site does not mean concealing its constraints. The main technical challenge of Saharan storage is the management of sand winds, which can occur during sirocco episodes between March and June. Fine Saharan sand, particularly abrasive, attacks glazing surfaces, paints and turbine blades when aircraft are not properly protected.
The industry has long developed operational responses to these hazards, notably codified in the AFRA Best Management Practices and in the storage manuals of major airframers:
- Semi-covered hangars with tensile structures, which protect fuselages from sand deposits and direct UV without the logistical burden of a fully enclosed hangar.
- Thermo-reflective covers on cockpits, windows and radomes, limiting dust penetration and stabilising internal temperature.
- Intake covers and exhaust plugs on every engine and APU, replaced on a strict schedule defined by the engine manufacturer's manuals.
- Light differential pressurisation of cabins and cargo holds to prevent fine particle ingress.
- Periodic rotation of landing gears and control surfaces to prevent permanent stress points.
These solutions are well proven in Middle Eastern storage sites that face very comparable climatic constraints. Far from being a handicap, Saharan storage practice has actually advanced the global state of the art.
Operating costs: land, sovereign energy, trained workforce
The economic advantage of southern Algeria is not limited to entry logistics. Three other variables play in its favour in a structural way.
First, the cost of industrial land in the Sahara is incomparable with what California or Arizona offer. Available surfaces, the accessibility of existing runways inherited from Algerian military and civil aviation, and the policy of the Algerian State in favour of economic diversification in the South create a land framework well suited to heavy industrial projects. The Mojave and Pinal sites, by contrast, face increasing land pressure linked to the residential expansion of Los Angeles and Phoenix.
Second, energy. Algeria produces more natural gas and electricity than it consumes, and the south of the country is becoming one of the largest photovoltaic solar reserves in the world. A Saharan industrial site can thus be supplied with low-carbon electricity at a cost between one-third and one-half of Californian rates. This matters particularly for paint shops, test benches and the future recycling lines, which are intensive consumers.
Third, the workforce. Algeria has trained aerospace technicians and engineers for several decades, a significant share of whom currently work in Europe. The return of this technical diaspora, combined with new graduating cohorts from Algerian schools, draws a qualified talent pool that constitutes one of the country's most durable comparative advantages in the MRO segment.
The Algerian regulatory framework
No storage and maintenance site can be established without a solid regulatory framework. In Algeria, the ANAC (National Civil Aviation Authority) oversees the certification of maintenance organisations, the approval of long-term storage plans and the issuance of operating permits. ANAC bases its regulatory corpus on the annexes of the Chicago Convention and on ICAO Doc 9760, which provides internationally recognised technical equivalence.
Algerian organisations can also obtain EASA Part-145 recognition, through bilateral agreements between the Algerian State and the European Union, as well as FAA Part 145 and FAR Part 91 approvals for specific storage and return-to-service operations involving US-registered aircraft. The European EU 261 regulation on passenger rights, although it does not directly concern storage, is among the references regularly integrated in service contracts with European carriers.
This regulatory fabric — ANAC first, then ICAO, EASA, FAA — is today fully mastered by the Algerian aerospace ecosystem. It guarantees international operators that the technical standards applied on Algerian soil are aligned with the best global practices.
Why AéroNéo is positioning the Algerian Sahara on 300 hectares
It is within this context that AéroNéo Algeria has initiated the pre-launch of its Saharan industrial campus project. The company, currently being structured, is targeting a concession on an airport site of around three hundred hectares belonging to the Algerian State, sized to ultimately accommodate several hundred aircraft in long-term storage, several heavy maintenance lines (C-check, D-check), a P2F conversion workshop and a recycling facility aligned with the AFRA BMP standard.
The project is not yet operational: actual operations will begin after the granting of administrative authorisations, the airport concession, and the approvals of the ANAC Algeria as well as the relevant EASA and FAA recognitions. But the industrial trajectory is set: making southern Algeria the Mediterranean and African counterpart to what Mojave represents for the North American market — not by imitation, but in coherence with a geography, a climate and a strategic position that, objectively, allow for it.
"The Algerian Sahara does not seek to be another Mojave; it is its own reference, closer, more central, and carried by a national aerospace sector under full structuration." — AéroNéo internal note, May 2026.
Storing an aircraft is not a passive logistical act; it is an industrial decision involving several million dollars per airframe and several years of cycle. Choosing the site means choosing the conditions in which an aerospace capital asset will age, wait and depart again. At the scale of a European or African fleet, the Algerian Sahara brings together every variable — climatic, geographic, energetic, regulatory — to become, in the decade ahead, one of the new global pivots of aircraft storage and transition.
