The Carter administration continued its congressional lobbying yesterday for lifting the Turkish arms embargo, as top civilian and military leaders made the case before a generally sympathetic Senate Armed Services Committee.
Only Sen. John C. Culver (D-Iowa) expressed skepticism about the need for Turkey to receive more American weapons than it already has been getting under the relief features of the embargo imposed in 1975.
After Defense Secretary Harold Brown said that Turkey has gotten $425 million during the past three years and two months, despite the embargo, Culver questioned whether it would be in the national interests of either the United States or Turkey to provide any more weaponry.
"What kind of wish list are we confronting?" Culver asked.
Culver also noted that during the embargo, Turkey had received $30 million in American arms from a NATO purchasing agency called NAMSA, for North Atlantic Military Supply Agency.
Secretary of State Cyrus R. Vance and Brown said that the Carter administrtion, right after learning last year about the NAMSA purchases for Turkey, charged that amount against the limit of $175 million a year for Turkish arms purchases allowed under the embargo.
Gen. Alexander M. Haig, NATO commander, said under questioning by Culver that he "was not aware of" NAMSA's purchasing for Turkey.
At another point in the hearing, Haig warned that, if the arms embargo is not lifted, Turkey might by late summer eject the rest of American forces in that country.
Gen. David C. Jones, newly named chairman of the Joint Chiefs of Staff, told the committee that if more arms are not sold to Turkey its forces will deteriorate.
"The implications of such a posture would be grave," Jones said, "not only for Turkey, but for Greece, NATO and the U.S."
