Telefónica and NOS to jointly develop defence connectivity capabilities

Telefónica and NOS have agreed to jointly develop defence connectivity capabilities, pairing Spain's largest telecom operator with one of Portugal's principal converged service providers in a segment that European carriers increasingly treat as a growth market.

The two operators confirmed the cooperation this week. The arrangement commits both companies to building connectivity products and services designed specifically for defence-sector customers, an area in which commercial operators have historically played a limited and tightly regulated role.

What does the deal cover?

The agreement centres on joint development. Both operators will work together on connectivity capabilities aimed at defence applications, rather than one side simply reselling the other's technology.

Neither company has yet published a detailed scope. The public announcement establishes the direction of travel: shared work on secure, defence-grade connectivity built on the operators' existing network assets in their respective home markets.

Why pair a Spanish operator with a Portuguese one?

Telefónica operates in Spain; NOS operates in Portugal. The Iberian pairing gives the cooperation a natural geographic logic. Both countries are NATO members, and both have been expanding defence procurement budgets since Russia's full-scale invasion of Ukraine in 2022 pushed European governments to accelerate military spending.

For carriers, defence work offers revenue that is less exposed to the price competition grinding down consumer mobile and broadband markets. Governments pay for resilience, redundancy and security guarantees rather than for the lowest headline tariff.

Commercial reality versus positioning

The announcement is a statement of intent, not a contract award. No financial terms, revenue targets or delivery timelines accompanied the initial disclosure, so investors have little yet to price in.

What it signals is portfolio strategy. Operators across Europe, including Telefónica, have spent the past several years courting public administration and enterprise segments to offset stagnating retail revenue. Defence connectivity sits at the premium end of that push, where security accreditation and sovereign network credentials matter more than price.

The marketing message from both operators will emphasise trusted, resilient infrastructure. The commercial test will be whether the joint capability translates into actual defence contracts, and on what scale, in either market.

What does this change for the two operators?

In the near term, very little operationally. Customers of either company will see no change to existing services. The significance is strategic: it gives Telefónica a partner in a neighbouring NATO market and gives NOS, the smaller of the two, access to development work it might struggle to fund alone.

For the European telecom sector, the deal adds to a small but growing pattern of cross-border operator cooperation on sovereign and security-sensitive connectivity, a segment regulators watch closely because defence networks often carry procurement and security conditions that ordinary commercial networks do not.

What comes next

The immediate next steps are technical and commercial definition: which capabilities are developed first, how they are certified for defence use, and which government customers the partnership approaches. Further detail on scope and financial commitments is expected as the cooperation moves from announcement to execution.
