BONN, JAN. 30 -- Germany offered Israel a $666 million defense package today that includes Patriot missiles, poison-gas detection gear and aid in building two submarines.

Chancellor Helmut Kohl's government said medicines and medical equipment also would be delivered to Israel.

Bonn said it also would give Britain $533 million to help pay that country's war expenses.

The package for Israel includes financial help to build two submarines at German shipyards, and a battery of U.S.-made Patriot anti-ballistic missiles with eight launchers to strengthen Israel's air defenses, government officials said.

Another official, speaking on condition of anonymity, said German soldiers would not be sent to Israel to operate the missile systems. The government has said Germany's constitution forbids sending troops outside NATO territory.

Several Patriot batteries, operated jointly by U.S. and Israeli crews, already have been deployed around Israeli cities. Iraq has launched at least seven Scud attacks in 11 nights against cities in northern Israel, but most of the missiles were intercepted and destroyed. Four persons have died directly or indirectly as a result of the Scud attacks.

Kohl's spokesman, Dieter Vogel, said: "The federal government is acting in accordance with the special responsibility which it . . . feels toward Israel."

The submarine offer would need approval by German parliamentary committees to meet export regulations, Vogel said. However, little difficulty is anticipated in gaining the needed support.

Israel has been pressing Germany for years for help in building submarines.

Germany has been embarrassed by reports that German firms helped Iraq improve its rockets, produce chemical weapons that could be used against Israel and build Saddam Hussein's bunker in Baghdad.

For many Jews, Iraqi poison gas and rockets made possible by German know-how are chilling reminders of the Nazi Holocaust.

The announcement followed negotiations with an Israeli delegation on what Germany might provide to help protect the Jewish state.

Vogel said Germany also is sending eight Fox armored vehicles designed to detect poison gas, and 50 similar vehicles from stocks of the former East German army.

German army instructors will teach Israeli teams how to operate the vehicles, he said.

Officials confirmed a news report that the export firm Havert received $1 million in government-backed credit guarantees to export compressors that have been used to improve Iraqi Scud rockets.

The government is investigating whether Havert knew the compressors were used for the rockets, said a Finance Ministry official.
