Breaking Defense reported that Greece chose the Millennium to replace its aging Lockheed Martin C-130H fleet.2 The purchase also offers a refueling role: Embraer says the aircraft can operate as a tanker when configured with quick-installation air-to-air refueling equipment.1

According to Breaking Defense, a Greek parliamentary committee reportedly approved procurement and follow-on support of three aircraft in June, with an expected budget of roughly €600 million.2 Embraer's signing announcement gives no contract value.1

The Greek order adds a delivery commitment beginning in 2027, when Embraer says the Hellenic Air Force will receive its first aircraft.1 Breaking Defense reports that Embraer aims to increase annual C-390 production to 10 aircraft by the end of the decade.2

Portugal authorizes Embraer KC-390 purchase for resale to Greece

Greek sale revenue is to fund three aircraft and associated support, but the government-to-government contract remains to be concluded.

Portugal has authorized the purchase of three Embraer KC-390 transports and an entry-into-service logistics package for resale to Greece.1 The authorization allows spending of up to €532.9 million plus VAT with a consortium of Embraer S.A. and Embraer Portugal S.A.1

Greece formally asked Portugal for the aircraft, training and initial logistics support. The resolution provides for Greek sale revenue to finance the operation entirely, although the government-to-government contract is still to be concluded. It does not state the price Greece would pay.1

A separate authorization allows Portugal's Air Force to spend up to €57.1 million plus VAT on electronic warfare equipment, training, logistics support, technical support teams in Greece and program management. The resolution estimates the overall charge at about €590 million, with spending spread over 2026–2031. The Council of Ministers approved the resolution on October 14, 2026; it was published in the official gazette on October 22.1

Portugal established the broader purchase route in 2025, when it exercised an option for a sixth KC-390 and secured options for up to 10 additional aircraft for European or NATO nations. Those nations could buy through the Portuguese state under government-to-government arrangements; the resolution does not specify whether the Greek aircraft would use those options.1

The planned sale links an export purchase to Portugal's continuing investment in the KC-390 Program. The resolution earmarks all sale revenue for the program, covering the aircraft and associated support as well as its continuity and capability evolution.1

Viasat wins contract for Space Data Network’s mission operations hub

The award includes a $115 million initial task order to design, field and scale the center, under a contract with a $450 million ceiling.

Space Systems Command (SSC) awarded Viasat a competitive indefinite-delivery/indefinite-quantity contract for the Space Data Network Backbone’s Mission Operations Center, the command announced Nov. 5, 2026. The contract carries a $450 million maximum ceiling and a $115 million initial task order to design, field and scale the center.1

Viasat, Inc. will serve as the network and mission system integration partner

Viasat will serve as the network and mission system integration partner as SSC expands its open-architecture ecosystem across multiple space-segment providers. SSC plans to bring mission integration, network operations and data transport management together through the center.1

The effort builds on the multi-vendor acquisition strategy demonstrated in the Space-Based Sensing and Targeting portfolio’s earlier Delivery Order 2 and Delivery Order 3 work. That work involved Amazon LEO for Government, Lockheed Martin, Northrop Grumman, Rocket Lab and York Space Systems.1

Breaking Defense reported that the center will serve as the network orchestration hub for the backbone, a low Earth orbit constellation being built by SpaceX. The network’s near-term focus will be supporting the Golden Dome missile defense initiative, the outlet reported.2

DefenseScoop reported that earlier this year the Department of War awarded SpaceX a $2.3 billion contract to deliver a fully operational backbone prototype by the end of 2027.3

The center is intended to integrate mission systems across multiple constellations and providers.1 Breaking Defense described network orchestration as autonomously shifting data among satellite constellations and ground stations when congestion or jamming slows transmission.2
