U.S. Makes F-35 Push As Portugal Weighs F-16 Replacement

What decision is Portugal facing about replacing its F-16 fighter fleet?

Portugal is deciding how to replace its F-16AM/BM fighters. It can keep investing in older fourth-generation aircraft or move to the F-35A, a fifth-generation fighter. The choice matters because the F-16s remain useful but increasingly need expensive upgrades to stay competitive.

The current fleet still relies on the old AN/APG-66(V)2 radar. Portugal could replace it with an AESA radar such as the APG-83 and continue upgrading avionics, sensors, communications, and self-protection systems. Structurally, the aircraft could potentially serve into the mid-2040s, but relevance would require sustained investment.

Portugal has not formally launched a replacement competition. It is seriously considering the American F-35 proposal, while Eurofighter Typhoon, Rafale, and Gripen E are also in the European competition. Airbus plans to offer financing, industrial participation, and broader military cooperation alongside the Typhoon.

What is the F-35A, and what does it mean for a fighter to be fifth-generation?

The F-35A is the conventional takeoff version of the F-35 fighter. The article describes it as a fifth-generation aircraft built around low observability, sensor fusion, advanced electronic warfare, and networked operations. These features are intended to help it operate in heavily contested airspace and share information effectively.

Low observability makes the aircraft harder to detect, while sensor fusion combines information from onboard and external sources into a clearer picture. Electronic warfare can help manage or disrupt threats. Networked operations connect the fighter with other aircraft and forces, allowing information to move quickly across a NATO force.

The article presents the F-35A as a major step beyond Portugal’s F-16AM/BMs. It would give Lisbon access to a growing European F-35 community and a fighter designed for modern networked warfare. The trade-off is choosing a new fifth-generation system instead of extending a familiar fourth-generation fleet.

How large is Portugal's current F-16 force, and how widespread is the F-35 across Europe?

Portugal’s active force consists of 25 modernized F-16AM/BMs. It has 21 single-seat F-16AMs and four two-seat F-16BMs, based at Monte Real Air Base. Portugal originally acquired 45 F-16A/B Block 15 aircraft through the Peace Atlantis programs, but 12 former Portuguese aircraft were later transferred to Romania.

The Portuguese fleet includes aircraft from two batches. Twenty new-build aircraft arrived beginning in 1994. In 1999, Portugal received 25 former U.S. Air Force aircraft, many of which underwent modernization to the F-16AM/BM standard. Twelve were later transferred to Romania in 2016 and 2017, with Romania ordering five more in 2019.

The F-35 has a much wider European footprint. More than 900 aircraft are already in service or on order across Europe, according to John Arrigo. Washington argues that joining this community would give Portugal an interoperability advantage within NATO.

What alternatives to the F-35 are being considered, and how do the Eurofighter Typhoon, Rafale, and Gripen E differ from it?

The F-35 is competing against three European fighter options: the Eurofighter Typhoon, Dassault Rafale, and Saab Gripen E. The article describes the F-35 as a fifth-generation aircraft centered on low observability, sensor fusion, electronic warfare, and networked operations. It does not assign equivalent technical descriptions to the three alternatives.

The clearest difference in the article is therefore generational and design emphasis. The F-35 is presented as a stealth-focused fifth-generation system. The Typhoon, Rafale, and Gripen E are presented as competing European choices, but the source does not compare their radar, stealth, weapons, or electronic-warfare systems in detail. Any fuller comparison would require additional information beyond this article.

Competition is becoming more intense. Airbus plans an unsolicited Typhoon proposal for late October or early November. Its package is expected to include aircraft, financing, industrial participation, and wider military cooperation, giving the European bid a broader structure than an aircraft-only offer.

What would Portugal gain—and what strategic commitments would it make—by joining the growing European F-35 community?

Portugal would gain access to a fifth-generation fighter designed for low observability, sensor fusion, advanced electronic warfare, and networked operations. The aircraft would fit naturally into NATO, where more European air forces are adopting the F-35. Washington says this shared community would provide Portugal with a substantial interoperability advantage.

That advantage would build on Portugal’s existing NATO role. Portuguese F-16s have repeatedly flown air-policing missions in the Baltic States, Iceland, Romania, and Poland. An F-35 fleet could connect Portugal more closely with other European operators using the same aircraft and support a common approach to networked operations.

The article does not list specific contractual obligations or basing commitments from joining the F-35 community. Strategically, however, the choice would commit Portugal to replacing its current fourth-generation force with an American fifth-generation system. Lisbon must balance that alignment against competing European offers and the cost of sustaining its existing F-16s.

Why might choosing a European fighter offer Portugal industrial and political benefits even if the F-35 offers advanced military capabilities?

A European fighter offer could give Portugal benefits beyond combat performance. Airbus says its Typhoon proposal will include financing, industrial participation, and broader military cooperation. Those elements could support Portuguese economic and defense-industry interests while giving Lisbon a closer relationship with European partners.

The mechanism is the structure of the offer. Instead of selling only aircraft, Airbus is expected to combine the Typhoon with financial terms, work for industry, and wider defense ties. Such a package could make the decision more attractive to national policymakers, especially when Portugal is choosing a long-term fleet and partnership.

The article does not promise specific jobs, investments, or political outcomes for Portugal. It also does not say that European fighters would match the F-35’s stated low observability, sensor fusion, or networked capabilities. The choice therefore involves comparing advanced military capability with the industrial and cooperation benefits offered by European competitors.

How do modern combat aircraft use stealth, sensors, electronic warfare, communications, and networked operations to find and defeat opponents?

Modern combat aircraft use several systems together to find and defeat opponents. Sensors detect aircraft, weapons, and other threats. Low observability reduces the chance of detection. Communications move information between the fighter and other forces. Together, these tools help pilots build a clearer picture of the battlespace.

Sensor fusion is the key mechanism. It combines information from multiple sensors and networks into one usable picture, reducing the need for pilots to interpret separate displays. Electronic warfare helps the aircraft protect itself, manage hostile signals, and potentially interfere with an opponent’s systems. Networked operations let forces share information and coordinate actions more quickly.

The article identifies all these ideas in describing the F-35A: low observability, sensor fusion, advanced electronic warfare, and networked operations. Portugal’s F-16s already use targeting pods, helmet-mounted cueing, and guided weapons, but their old radar remains a limitation. Moving to the F-35 would shift the force toward a more integrated fifth-generation model.
