A breakdown of Iran's missile arsenal:
SAJJIL 1 and 2:
The Sajjil 2 is Iran's most advanced two-stage, surface-to-surface missile. It is powered entirely by solid fuel, which increases the weapon's accuracy. The missile has a potential range of 1,200 miles (2,000 kilometers), putting Israel, parts of southeastern Europe and U.S. bases in the Middle East within range.
The Sajjil 2 is equipped with an improved guidance package compared with the Sajjil 1, and can be launched in a matter of minutes. Experts say the Sajjil-2 is more accurate than Shahab missiles and its navigation system is more advanced.
The medium-range ballistic missile can strike targets within a radius of 800 miles (1,300 kilometers). The model is derived from the North Korean No-dong missile and is considered to have a low accuracy rate.
Shahab means "meteor" or "shooting star" in Farsi.
Variant of the Shahab-3 model, but lighter and with a range of 1,110 miles (1,800 kilometers).
The liquid-fueled Shahab-3B has a range of 1,200 miles (2,000 kilometers).
The single-stage, liquid-fuel missile is said to have a range of 310 miles (500 kilometers). Iran purchased the weapon from North Korea in the early 1990s. Also known as the Scud-C.
A short-range, solid-fuel missile. Versions of the Zelzal, which means "earthquake" in Farsi, have ranges of 130-185 miles (210-300 kilometers).
Iran's Revolutionary Guard test-fired the Zelzal from a multiple launcher on Sunday for the first time.
One of Iran's short-range missiles, the solid-fuel Fateh can strike targets up to 120 miles (193 kilometers) away.
Fateh means "conqueror" in both Farsi and Arabic.
Iran has had the Chinese-manufactured Tondar in its arsenal for many years. It is a solid-fueled missile with a range of about 93 miles (150 kilometers).
Tondar means "thunder" in Farsi.
