Tu-144LL – One Tu-144D aircraft (СССР-77114 [c/n10082]) converted to a flying laboratory with four Kuznetsov NK-321 afterburning turbofan engines and re-registered RA-77114. The first flight took place on 29 November 1996 with the 27th and last flight on 14 April 1999.

Tu-144LL的機體和量產型Tu-144大致相同，但使用來自Tu-160超音速戰略轟炸機的NK-321引擎，每具推力超過50,000磅，是Tu-144所使用過之中推力最大的引擎。 收藏品
