Iran on Saturday said that its new cruise missiles would be unveiled by next week, ISNA news agency reported.
A Defence Ministry spokesman said the new, longer-range missiles would be unveiled on Monday, which is also the annual Defence Industry Day, but provided no further details.
With a range of up to 2,000 kilometres, the Shahab-3 ballistic missile is Iran's longest-range missile.
Western nations are concerned about the country's missile programme, especially the Shahab-3 missile, which could reach any part of Israel.
