About those rockets ...

The Jerusalem Post is reporting that the rockets that struck in Haifa (Israel) were Katyusha rockets--with a substantially larger payload than the ones flying at Israel from Gaza.
Whoops--here's another report of a Katyusha rocket attack.

Here's a little bit about the Katyusha rocket:

Description: Katyusha is the generic name for a family of self-propelled artillery rockets originally developed and deployed by the Soviet army. The first Katyusha was deployed in the 1940's, and the most common version is 122-caliber model fired from a BM-21 truck equipped with 40 rockets. Katyusha rockets come in light and heavy varieties that weigh between 46 and 77 kilograms, are 1.9 to 3.2 meters in length, and have a range of 14,000 to 20,000 meters. Katyushas carry fragmentation, incendiary, or chemical warheads and are fired in salvos, 'rippled' sequences, or individually.

Notes: Many nations including Iran and the former Czechoslovakia have produced indigenous versions of the rockets and launchers. Iran exports Katyushas to the Lebanese Hizbollah that have been fired against Israeli soldiers and civilians in South Lebanon and Northern Israel. During the Cold War Russia sold Katyushas to Afghanistan, Angola, Czechoslovakia, Egypt, East Germany, Hungary, Iran, North Korea, Poland, Syria, and Vietnam.
