Training was in play at Local and Ground all day.  There was flow with delays to ZZZ.  Aircraft Y was taxied to Taxiway L short of M for eventual taxi via M to 1L for departure. Aircraft X was taxied to Runway 1R on the SSTIK4; which requires a red 'R' if requested/required by the pilot.  It is unknown at this point if that was the case.  My only assumption is that the Ground CPC-IT taxied the aircraft incorrectly to Runway 1R and the OJTI did not notice.  As their flow time came up; Local CPC-IT taxied Aircraft Y across Runway 1R at M and LUAW Runway 1L.  Aircraft X was given Runway 1R LUAW.  The CPC-it then; unbeknownst to the OJTI; launched Aircraft X on the SSTIK4; and shortly thereafter launched Aircraft Y also on the SSTIK4.  The only reason I became aware is when I heard the CPC-IT issuing visual separation and the Local Assist coordinating the same with NorCal.  When I looked up at the display; the aircraft were approximately 2 miles in trail with Aircraft Y lower and following to SSTIK.  Of note; with OJT occurring on both Local and Ground simultaneously; and Local Assist open; but apparently not engaged dynamically; the FLM could not possibly monitor both positions and all that the Local Assist was doing.  Subsequent discussion by the Local Control OJTI dictated that they were sorry; as they missed it and 'Use of RNAV To... will save you every time.'  This has been my complaint about people who refuse to use it and ignore that its use will in fact keep this exact scenario from occurring.  The numbers of neigh-sayers are reducing thankfully and we will eventually have the majority compliance.The traffic has picked up over 700 operations a day a few days of the week and is expected to get busier by the month this summer.  Use RNAV To... and; when working as OJTI; pay attention to what the CPC-IT is doing.
