Iran Fires 180 Ballistic Missiles at Israel; Israel Strikes Back at Iranian Soil

The six months between Iran's first direct strike on Israel in April 2024 and its second in October 2024 were defined by a sequence of escalations that made a second Iranian attack not merely plausible but, in the IRGC's strategic calculus, obligatory. In July 2024, Hezbollah's military commander Fuad Shukr was killed by an Israeli strike in Beirut; within hours, Hamas political leader Ismail Haniyeh was assassinated in Tehran itself — an operation conducted inside the Iranian capital that constituted a profound intelligence and security failure whose domestic political consequences demanded a response. In August and September, Israeli operations in Lebanon intensified: the assassination of Hezbollah Secretary-General Hassan Nasrallah on September 27 removed Iran's most important and longest-serving proxy partner and decapitated the organisation that had constituted the western pillar of Iran's deterrence architecture. Nasrallah's death was not merely the loss of an ally — it was an operational demonstration that Israel was systematically eliminating the network of deterrent threats Iran had spent decades constructing around its borders. The IRGC's internal logic was clear: every unanswered Israeli escalation made the next one more likely and degraded Iran's reputation as a power whose retaliation threats carried credible weight. The October 1 attack was framed by Tehran as Operation True Promise II — a direct successor to April's True Promise I — and designed as a deliberate demonstration of capability improvement over the first strike.

The October 1 salvo involved approximately 180 ballistic missiles, and its design addressed the tactical shortcomings identified in April's largely intercepted barrage. Iran deployed a higher proportion of hypersonic-trajectory missiles, including variants of the Fattah-1 and Kheibar Shekan, which flew faster and on flatter trajectories than the Shahab-3 derivatives that had constituted the April attack's backbone — characteristics that reduced the engagement window available to Israeli Arrow-3, Arrow-2, and US THAAD batteries. The salvo was preceded by a short-warning window that compressed Israeli and American defensive reaction time. Unlike April's heavily telegraphed operation — which Iran had announced in advance and notified through back-channels to give regional actors including Jordan and the United States preparation time — the October strike was launched with minimal prior notification, a deliberate choice reflecting the criticism within IRGC command that April's performance had been degraded by Iran's own transparency. Several missiles reached their intended targets, striking the Nevatim air base in the Negev from which Israeli F-35s had conducted the Rafah operations, and causing damage to facilities at Tel Nof. Israeli casualty figures were not formally released, but explosions at military installations were documented by open-source imagery. The combination of improved missiles, compressed warning time, and the decision to omit advance coordination through regional back-channels produced a more operationally effective strike than April, even as the overall interception rate remained high.

Israel's retaliation on October 26, 2024 marked a genuinely new threshold in the conflict's escalation: Israeli Air Force F-35I Adir aircraft penetrated Iranian airspace and struck military installations inside Iran for the first time in the conflict's history — the first Israeli aircraft to operate inside Iranian territory in decades of adversarial history. The targets included radar and air-defence systems protecting nuclear facilities, surface-to-air missile batteries, and IRGC military infrastructure in provinces including Tehran, Khuzestan, and Ilam. The operation demonstrated that Iranian air defences, which had successfully tracked but not fully intercepted Israeli munitions in the April exchange, could not prevent Israeli aircraft from operating within Iranian airspace when stealth characteristics and electronic warfare were combined with sustained planning. Iran's response to the October 26 strikes was measured — public statements from the IRGC vowed retaliation at a time and manner of Iran's choosing, but no immediate escalation followed. The October exchange established the parameters that would define the conflict's subsequent trajectory: both sides had now struck each other's territory directly with aircraft and ballistic missiles, the deterrence architecture that had separated Iranian and Israeli military action for decades had been structurally dismantled, and the question was no longer whether a further escalation would occur but what the triggering conditions and scale of the next exchange would be. The Twelve-Day War of June 2025 was, in this sense, the direct military consequence of October 2024 having demonstrated to both sides that direct reciprocal action was the conflict's operating norm. The Israeli government's decision to strike inside Iran proper on October 26 also had an internal Iranian political consequence: it strengthened the IRGC's argument that diplomacy had failed to deter Israeli military action and that only the credible threat of overwhelming retaliation — including nuclear weapons capability — would produce genuine deterrence. The IRGC used the October exchange as evidence in internal debates that Iran needed to accelerate its nuclear programme rather than offer concessions, a position that hardened Iran's negotiating posture in the months before the Twelve-Day War and narrowed the already-limited space for diplomatic solutions to the nuclear question.
