A later assignment placed him on a ship that carried soldiers returning from France.
Mr. Jaspan's RCA career was interrupted by his 1943-46 Navy service, but he returned as an RCA wireman while earning a bachelor's degree in accounting at Temple University in 1952, his son said.
His most significant work for RCA was with the Apollo program, which ran from 1963 to 1972, sending manned and unmanned flights around the Earth and to the moon.
"He had a top-secret security clearance, which permitted him to work on classified programs at RCA" involving Apollo communications systems, his son said.
But when his wife, Shirley, went off to college to earn her bachelor's and master's degrees in the late 1950s and early 1960s, his son said, Mr. Jaspan became "the original Mr. Mom," cooking meals and doing housework.
"He was a regular Joe who made everyone feel special," his son said.
Mr. Jaspan had been chaplain for Jewish War Veterans Post 126 in Cherry Hill since 1995, and cochaired its annual Veterans Day service at Temple Beth Sholom in Cherry Hill, where he helped maintain equipment such as sound systems.
He assisted with the annual placement of flags at grave sites of Jewish veterans at Crescent, Locustwood, and Beverly National cemeteries.
He helped with bingo parties sponsored by Post 126 at the New Jersey Veterans Memorial Home in Vineland, and assisted with the annual USO gala dinner dance sponsored by the post and with its poppy sales to support its charities.
Besides his son, Mr. Jaspan is survived by sons David and Michael, eight grandchildren, and a great-grandson. His wife died in 1991.
A visitation was set from 9 a.m. Sunday, Sept. 8, at Platt Memorial Chapels, 2001 Berlin Rd., Cherry Hill, with Masonic services there at 9:30 a.m., Jewish War Veterans services at 9:50 a.m., and funeral services at 10 a.m. Interment with military honors is to follow at Crescent Memorial Park, Pennsauken.
