Defence minister stresses airspace sovereignty amid public debate over new US defence partnership.
Indonesia has made no binding commitment to grant US aircraft overflight access, Defence Minister Sjafrie Sjamsoeddin told Parliament, clarifying that his recent discussions in Washington produced only a non‑binding letter of intent.
Letter Of Intent, Not Binding Agreement
Speaking to Commission I of the House of Representatives on May 19, Defence Minister Sjafrie Sjamsoeddin said Indonesia has not committed to any US overflight arrangement, emphasising that he and US counterparts had signed only a letter of intent on overflight clearance during his visit last month. “This is a letter of intent, not a letter of commitment,” he said, stressing that Indonesia has “not made any commitment whatsoever” on airspace access.
Respect For Sovereignty And Legal Frameworks
Sjafrie said the document explicitly affirms both countries’ respect for territorial integrity and sovereignty, and outlines mechanisms and standard operating procedures that must comply with Indonesian and US laws. He underlined that Indonesia continues to “safeguard the constitution and protect our national interests” in all defence cooperation.
How The US Request Arose
According to Antara, the issue was first raised by US Secretary of Defence Pete Hegseth during a bilateral meeting on the sidelines of the ADMM Plus in 2025, when Hegseth asked whether US aircraft could transit Indonesian territory for urgent purposes while fully observing Indonesian regulations. Sjafrie said he told Hegseth he would first consult President Prabowo Subianto, describing him as the supreme commander of the Indonesian Armed Forces.
Talks, Proposal And Clarification
Sjafrie said US officials visited Indonesia in February with a proposal letter on overflight access and later invited him to the US “to discuss it, not to decide it.” He reiterated that last month’s meeting resulted only in a letter of intent. He also disclosed that Washington has asked Indonesia for help locating and repatriating the remains of American soldiers who died in World War II on Morotai Island, stressing that Jakarta weighs all cooperation proposals against its constitutional and strategic priorities.
Context Of MDCP And Public Debate
The minister’s clarification follows public concerns about Indonesian airspace control after Jakarta and Washington signed the Major Defence Cooperation Partnership (MDCP) in April 2026. Sjafrie said the explanation was necessary to dispel misperceptions that MDCP or the letter of intent had already opened Indonesian skies to US military overflights, insisting that any such step would require further internal decision-making and must not compromise sovereignty.
By drawing a sharp line between a non-binding letter of intent and any formal overflight agreement, Jakarta is signalling that airspace sovereignty remains a red line even as defence ties with the US deepen under the MDCP. For Indonesians and Singaporeans, the episode highlights how regional states are trying to balance great-power partnerships with constitutional constraints and public sensitivities over foreign military presence.
