44P5H2V0 is an unnamed 2c/5 orthogonal spaceship discovered by Dean Hickerson on July 23, 1991, being the first 2c/5 spaceship to be found. Robert Wainwright and David Bell then found some small tagalongs that allowed the creation of arbitrarily large 2c/5 spaceships. These were the only known 2c/5 spaceships until the discovery of 70P5H2V0 by Hartmut Holzwart on December 5, 1992.

Goldtiger997 found a 131-glider synthesis for 44P5H2V0 on August 29, 2020. Tanner Jacobi improved the synthesis to 41 gliders the same day. ENORMOUS_NAME and iNoMed constructed a 44P5H2V0 gun on October 30.
