	History:
	Modified Class-III Star Trek: The Next Generation Technical Manual A class-4 probe was sent into a subspace disruption near station Deep Space 9 on stardate 46853. It was later learned this subspace disruption was a product of Jadzia Dax's imagination, generated by aliens from the Gamma Quadrant. DS9 "If Wishes Were Horses" Starfleet scientific instrument used for remote sensing studies. Star Trek Encyclopedia II The class-4 upgrades have been combined into a single new class-5-type hull casing. The previous primary mission for the class-4 involved close stellar contact at medium impulse velocities only. This had been to high-impulse study of subspace anomalies and other phenomena not usually encountered in normal space. Effective range is 7.23 x 107 and total delta-v is 0.98c. The power plant remains a vectored microfusion engine with a near-warp sustainer coil. Sensors include full subspace EM and seismicity detectors, zero-point vacuum energy detector, and protected temporal distortion sensors. Onboard data preprocessing is handled by a 15.9-kiloquad isolinear computer, and telemaetry is transmitted over a ruggedized STA radiating 20.6 megawatt over 14,776 channels.
