Iran still maintains more military capabilities than the White House and Pentagon have publicly admitted, according to multiple U.S. officials cited by CBS News.

Officials said about half of Iran’s ballistic missile stockpile remained intact at the start of the ceasefire in early April. Roughly 60% of the naval arm of the Islamic Revolutionary Guard Corps was also still in existence, including fast-attack boats.

Iranian air power was described as only significantly degraded, while about two-thirds of Iran’s air force was still believed to be operational. Officials also said Iran still retains thousands of missiles and one-way attack UAVs.
