The first Vanguard of the SRF's Peacekeeping fleet, Seralo-class MKI Heavy Cruisers embody the Senlani's defensive doctrine to the fullest extent possible. Although classified as a Heavy Cruiser, Seralo-class warships are extremely fast for their class: designed by the SRFDF for fast interdiction of capital and super-capital class warships that threaten the Senlani homeworlds. She was built from necessity under the looming shadow and constant threat of a Tyandirr invasion of the Sector Rim Nebula, skilfully and expertly crafted by the best Senlani draughtsman to stand as a stalwart bastion to their way of life.
Armed with a primary battery of High-Velocity Magneto-Plasma cannons on fast-tracking automated turrets, Seralo-class possess heavy firepower; able to go toe-to-toe with the most powerful enemy warships, while remaining fast and versatile to adapt to any developing situation.
As the backbone of the SRFDF, these warships are a common sight in Senlani space, patrolling both the inner and outer sectors under the watchful eye of the Defence Fleet, maintaining peace and order through force if necessary. As part of the SRF's commitment to the Vuljcyon-lead Six Trade Alliance, the SRFDF operates Seralo-class Heavy Cruisers along with their smaller escorts beyond the Sector Rim Nebula and well into the Deep Red and surrounding territories. However, due to the fragile nature of the relationship between the Senlani and the Tyandirr; SRFDF Task Groups rarely approach the Taran Nebula.
The Seralo MKI Heavy Cruiser was the first in the lineage of Fast Heavy Warships developed by the SRFDF. Newer MKII and MKIII variants have entered service with various enhancements but the MKI remains a reliable powerhouse of the Defence Fleet.
