Israel Monitors Egypt’s Growing Military Build-Up in Sinai Amid Cairo-Ankara Cooperation
Israel’s defense establishment is closely monitoring a significant and secretive military build-up by Egypt in the Sinai Peninsula, revealed through satellite imagery showing extensive underground bunkers, expanded airstrips, and advanced Chinese air defense systems. These developments mark a stark departure from the demilitarized status Sinai held under the 1979 Camp David peace agreement between Israel and Egypt. Analysts warn that the fortified complexes near key military airfields could store strategic weapons, including ballistic missiles, although definitive proof of missile deployment remains unconfirmed.
The Egyptian military presence in Sinai has surged to approximately 40,000 troops, the highest since the peace treaty, alongside deployment of HQ-9B Chinese air defense systems with a range of up to 300 kilometers. These enhancements shorten Israel’s warning time in case of sudden conflict escalation. Additionally, a large underground complex near Cairo’s new administrative capital underscores Egypt’s extensive investment in strategic subterranean infrastructure.
Compounding Israeli concerns is the growing military cooperation between Egypt and Turkey, historically adversaries, now conducting joint naval and air exercises since 2025. This partnership includes special forces training and defense agreements, raising alarms in Jerusalem amid already tense Israel-Turkey relations.
Israel has formally raised these issues with the United States and Egypt, demanding explanations for the military expansions, which Cairo denies, asserting the measures are defensive and aimed at combating regional terrorism and securing borders. Despite the tensions, Israeli security officials assess the likelihood of an imminent Egyptian attack as very low, viewing the build-up primarily as a deterrent strategy in a volatile Middle East.
However, experts caution against complacency, noting that the existing infrastructure enables rapid deployment of large forces, potentially altering the strategic balance. The situation remains fluid, with satellite surveillance continuing to track developments, while the fundamental question persists: is Egypt’s military expansion purely defensive deterrence or preparation for future conflict?
