Military bomb shelters

Hobbit House manufactures rapidly erected protective structures: a shelter is assembled from modules on site in the shortest possible time, and equipment can be moved inside for storage. The record for installing an above-ground shelter is 3 hours. The quality of Hobbit House shelters is confirmed by expert opinions and certificates, as well as by a full-scale test of the structure on a test range — direct fire from a tank (the video is on our YouTube channel). The shelter passed the test. Today our structures are used by the Armed Forces of Ukraine and the border guards to save soldiers' lives on the front line, within the first kilometres of the line of contact and in central Ukraine. The shelter has an arched roof, the most effective shape for reducing the impact of a blast wave and the load from weapons, for making munition fragments ricochet and for protecting against parts of building structures. Fortetsia 2.25 and 3.5 and Hobbit 2.0 passed a field test — the detonation of a 120 mm high-explosive mortar round: 500 kPa for Fortetsia 2.25 and 3.5, 300 kPa for Hobbit 2.0. Fortetsia 4.0 and 6.0 are rated at 100 kPa. For reference, an air blast wave of 100 kPa kills an unprotected adult, and 300 kPa destroys military equipment. 300 kPa is an overpressure of 30 tonnes per square metre. The shelters also have an expert opinion on the radiation protection factor (Kz), under which the modules may be used to build rapidly erected anti-radiation shelters with a Kz of at least 400 in accordance with DBN V.2.2-5:2023.

For the military, we offer a wide range of structures:

1. Hobbit underground shelter — for sheltering personnel. The simplest shelter consists of two parts, an upper and a lower one. Installation in a prepared pit takes minimal time. The structure is reinforced, withstands loads and protects against fragments in accordance with DBN V.2.2-5:2023.

2. Fortetsia above-ground fortified structure — the design most often requested by the military. Thanks to the high strength of its arched structure and its 300 mm walls, it is the strongest rapidly erected shelter made in Ukraine. The military usually bury it to stay unseen by the enemy and gain extra protection. Fortetsia comes in four sizes: 2.25, 3.5, 4.0 and 6.0 (the internal width of the modules in metres). Fortetsia 2.25 is best for small shelters (up to three modules). When more protected space is needed (warehouses, headquarters, field hospitals), modules with an internal width of 3.5 metres are more efficient.

3. Bastion shelter — the ideal option for protecting large vehicles, including armoured vehicles such as the Dutch-made YPR-765 infantry fighting vehicle now widely used by the troops. The internal width of the shelter is 3.5 metres; the blocks are 600 mm wide. This shelter is not rapidly erected: installation takes time, depending on the required size.

4. Firing positions. At the request of the military, Hobbit House LLC designs and, if needed, supplies reinforced-concrete firing positions to the Armed Forces of Ukraine. They allow soldiers to fire from protected space and have room for ammunition.
